You want to sell valuable us coins and you’re not sure how or where? In this post we offer a practical guide to sell your coins through a coin auction.

For some years now, this method of selling collector coins has been advancing steadily, and little by little, it is becoming the preferred method of selling coins for collectors, with a clear upward trend.

Most of the time selling a coin online is usually more advantageous than through a coin store

Which is the best coin auction?

The one that is most specialized in your coin collection. The rest of the conditions, if they are reasonable, are not so important.

There are many options for selling your old coins at auction. Here we give you elements, tips and guides to find the numismatic auction that best suits your collection.

The value in Auctions for coins

It seems obvious, but we are obliged to warn about this point because of the many times we have observed the opposite.


Sell legacy coins in online coin auctions

As a general rule, a person who has a coin collection that costs a significant amount of money, when he or she leaves that collection to a relative, usually informs the relative that the collection takes a lot of effort, both financial and in terms of time and study.

If we have inherited a number of coins and in no case have been advised that these coins are appreciated and expensive, it is quite possible that our relative simply enjoyed spending a few tens of dollars from time to time on a piece. Many collections are of great historical interest, but little value.

Before selling in a coin auction online

If we are not sure of the price of the collection we want to send to the auction house, a great idea is to choose four or five pieces that we consider to be the most valuable, and open a consultation with a professional. If you show interest in sending the collection to their company, they will advise you, and guide you in how to know the value of your coins and sell your collection.

Don’t forget that, with this sales system, the auction house is going to make more money the more expensive it is able to sell your coins.

Advantages of the coins auctions online

  • The currency has a visibility that is difficult to achieve with any of the alternative sales methods.
  • Auction houses offer the highest level of confidence to buyers. Customers know that the currency has passed through the hands of a professional and that this professional has authenticated it.
  • Competition among customers can cause some coins to be auctioned for prices far above their market price.
  • Ease for the seller. The company to which we consign the coin will be in charge of classifying it, grading it, photographing it, advertising it and managing the payment.

Disadvantages of coin auctions houses

  • They have a high commission load. Usually a major auction house charges a commission to the seller of between 5% and 20% of the auction price.
  • This will only work for coins with a high market value, or for quite a few coins with a medium market value. Auction houses require a minimum deposit of a significant amount around $5,000.
  • Payment is not usually immediate. Payment is not usually immediate. It is usually between 15 and 60 days from the date of the auction.

We have to consider that these inconveniences describe the general operation of the auction houses.

There can be exceptions… for example, in the first point that we describe the commission by sale, if the seller appears with a sufficiently important collection, the commission by sale will be 0% or even negative (some companies offer to their ceding companies more money than the auctions of their pieces reach).


Which coin auction site choose?

Well, we’ve already decided to sell the coin through an auction house, and now it’s time for a crucial decision. Where do I sell it?

As a rule, all auction houses are serious, professional companies. They are usually run by prestigious numismatists, and all of them are very reliable. They won’t fool us, they live off their image. Vico, Herrero, Pliego, Ibercoin, Aureo Calico, Cayón, Tauler y Fau or Soler y Llach auctions are some of the most popular in Spain.

However, there are a number of factors that should tip the balance when deciding on one company or another…

Find an auction house specializing in your type of valuable coins

If an auction house specializes in a particular series, collectors of that series will usually know about it and pay special attention to the auctions organized by that house.

Thus, the chances of our lot reaching a higher price are higher. We will list some of the most important companies, giving you some tips on which auction house to choose to sell your collection.

Top 4 U.S. Coin Auctions

Heritage Auctions Coins, world leader

The world’s largest numismatic house… no more words. They’ve auctioned off 10 of the 20 most expensive coins in history. Heritage Auctions specializes in high quality American and world coins. They have an impressive client list, and there is no amateur or professional coin dealer who does not know about them.

Stack’s Bower, antique coins auctions with guarantee

Another giant of the numismatic auctions. If Heritage has 10 of the 20 most expensive coins in history, Stack’s auctioned the three that fetched the highest price, with a combined total among the three of nearly $20 million. Also specialized in American coins or high quality world coins.

Daniel Frank Sedwick

Best choice if a coin collection is based on colonial Spanish currency or treasures recovered from shipwrecks. This house specializes in those series, and they are probably among the greatest experts in the world.

Ira & Larry Goldberg

They have fewer auctions per year than Heritage or Stack’s Bowers, but they are always chosen coins of exquisite quality. A good option for auctioning important collections, as they have a large customer base.


Where to auction your old coins in Europe

If our collection is based on international currency and very specialized in a particular country, we also have the option of sending it to a European house, where despite having a somewhat smaller portfolio of customers, it is natural that these customers are specialized in the national currency.

  • Kuenker (Germany). Probably the largest auction house in Europe, and the one that puts the best Central European coins up for auction
  • Spink (United Kingdom). Another European auction giant, founded in 1666, is not lacking in experience with its more than three and a half centuries of life. In addition to British currency, for cultural reasons they are also highly specialized in colonial currency.
  • Áureo & Calicó (Spain). The best option to sell a collection or a Spanish peninsula coin. The Spanish coin, thanks to its colonial past, is the second most collected in the world, since many countries, including the United States, used it before having their own national currency.
  • Varesi (Italy). The same level as the previous ones, but more specialized in its local currency. The best option for auctioning Italian coins or Italian coin collections of some importance.

All these companies are great professionals, with years of experience in the sector and a great prestige within the numismatic world at an international level. However, if you are a resident of another country, you can also look for some other options, as there are hundreds of possibilities, and usually all of them are equally valid.

Tips before sending your coins to coin auction sites

Let’s describe the usual operation we will have as cedents in an auction house when we put our coin collection up for sale. Bear in mind that different companies will use different protocols of action, and some of these points may vary a little. Once again, if you have any doubts, do not hesitate to call the company for information. They are always professionals, who are dedicated to this, and they will never put any obstacles in your way to inform you.

  1. The first point is to contact the auction company. We would recommend sending several emails to various companies, explaining to them our intention to sell a collection at an auction of theirs. In addition, we should send, if we have it, the cataloguing of the coins, and several photographs, both of the collection in general and of the coins that we consider more beautiful in particular.
  2. If you show interest in having our collection sent to you, we would recommend a telephone contact. There, we could be informed about several points of certain importance: The way of sending the collection, the commission to the seller, the way of payment and the term of payment.
  3. The next point would be to send them the coins, and at the same time they will send us an email with the cataloguing that their experts have done of our collection, the grading that they have estimated for our coins, and the starting price that they are going to put on the lots. This starting price is usually negotiable, and we can agree with the company if we do not agree with any of them. However, we always advise you to listen to the experts, because they are interested in maximizing the selling price, so they can maximize their profits.
  4. Finally, the auction will take place, and within the agreed period, we will receive payment for our collection.

How coin auctions work?

A numismatic auction has a fairly simple and easy to learn operation for regular buyers.

Types of coin auctions

A few years ago, there were two types of auctions. In-house auctions, which are the ones we usually see on TV, with the auction manager saying out loud the current bid and the buyers raising their hands to beat it. There were also online auctions. In this mode, bids were received in a sealed envelope, and the highest bid received simply won.

This last modality of numismatic auctions is more and more in disuse. With the implementation of new technologies, online auctions now have a live component, and the operation is exactly the same as a room auction, except that the management is exercised by a machine instead of a person.

Auction catalogs

Usually, companies print a catalog with all the catalogued, graded and numbered lots they are going to offer, and send it to their regular customers or to those people who might be interested in some currency. In this catalogue, it is announced when the auction will be opened for pre-bids, and when the live auction will take place.

The online bidding system

As soon as the pre-bids are opened, the company starts receiving bids for the lots. These bids can be made online, or by more traditional means such as sending a letter by mail or a phone call.

Usually, the day before the auction takes place, the previous bids are closed, and the lots go live with a starting price equal to the highest bid previously received. Some customers prefer to pre-bid, some others prefer to bid live, there are as many strategies as there are people, and none is more valid than the other.

Nowadays, practically all companies in the sector have developed a web or mobile app that allows customers to bid live without having to be present at the place where the bidding takes place. The big difference between live auctions and online auctions is the presence of an auctioneer and a live audience.

In addition, large companies tend to keep the best currencies for their live auctions, and the least important ones for online auctions, as the cost of developing them is much lower.

What is the starting price of an auction?

The starting price refers to the minimum amount at which the coin can be sold. Any price below that amount is not considered.

What are hammer and realized prices?

The hammer price is the maximum value that a buyer has offered for the piece. This hammer price ends the coin auction.

The price realized is the final purchase price of a lot. Includes the hammer price plus the buyer’s premium.

Besides, the buyers premium simply refers to a percentage additional charge on the hammer price of the lot that must be paid by the winning bidder. It is supposed to be charged by the auctioneer to cover administrative expenses. The buyer’s premium goes directly to the auction house and never to the seller.

Conclusion about Coins Auctions

In the coin sector, the starting price may or may not resemble the hammer price. It is usually related to the interest that the coin causes among the bidders. The higher the number of bids, the higher the auction price for coins will be. As a result, if there are hardly any bids, the hammer price will be very similar to the starting price.
