Proof Set Values: U.S. Valuable Proof Sets You Should Be Checking

Coleccionistasdemonedas.com has rated as the most valuable U.S. proof sets:

Although U.S. proof sets were initially produced by the United States Mint in the 19th century, it wasn’t until 1936 that proof sets, as we recognize them today, began to be sold and marketed to the general public. Furthermore, they have been continuously produced up to the present day.

These sets encompass a proof-quality specimen of each denomination minted in a given year, with values ranging from 1 cent to half a dollar. Some proof sets also incorporate the 1-dollar denomination when it has been a part of that year’s coin production.

The origin of these United States proof sets lies in the demand of coin collectors to have a proof sample of all the monetary values that were going to be put into circulation that same year.
Normally, between 1936 and 1951, proof sets were not sold completely in their case as we know them today, but each value was presented and sold separately, in a somewhat precarious presentation.

What coins are proofs?

Proof coins are specially made using polished dies and planchets (blanks) made of carefully selected and prepared planchets. The dies are treated with special chemicals to give them a mirror-like finish, while the planchets are also polished to create a smooth, reflective surface. The striking process for proof coins is done slower and with more significant pressure to make a sharper, more detailed image.
They are usually produced for coin collectors, distinguished from regular coins by their exceptional quality and beauty. They often feature frosted, raised design elements that contrast with the mirror-like background field and are struck multiple times to ensure superb detail and clarity.
These pieces are typically sold in unique sets or individually. They are often more expensive than their regular counterparts due to the extra effort and care that goes into their production.

Preserving your coins

In these early years, the values were preserved in cellophane envelopes, and each value was stapled in cardboard as a presentation. That is why it is common to find pieces from the early years with traces of adhesive, plastic, or paper stuck to them.
Due to certain factors, finding these early years’ values in their original packaging is becoming increasingly challenging. The passage of time causes the original presentation package to wear out, separating the set for a deal that interests a coin collector, sending the pieces to a TGP company for grading, etc.
Here we show an example of the 1936 United States proof set with its six values, from 1 cent to half a dollar, encapsulated as a set by NGC in preservations ranging from PR64 to PR67 in packaging made for the occasion by NGC:

Until 1968 the proof set coins were minted in Philadelphia, but in that year, production was moved to the San Francisco mint, easily recognizable by the appearance of the “S” mint mark on the coins.
Some proof coins are in high demand and have valuations well above the average price of the standard proof set. For example, we have very scarce sets, such as 1936, others made without the San Francisco mint mark or certain silver proof sets.

How much are U.S. Mint proof sets worth?

Are coin sets worth anything? Let’s see which are the five sets that have had the highest value in the market in the last years. Here’s an updated and fact-checked list of proof set values.

1. 1936 Proof Set – $ 35,250

We begin our list with 1936, the first year that U.S. Mint struck proof sets. Despite being the most frequent year in auction houses and sales, it is also the most valued by collectors.
The highest price ever paid for a 1936 proof set was reached in April 2015 in a lot of 5 values encapsulated separately by NGC and graded between PR66+ and PR67. The final price was $35,250.

According to the auction house, the coins of this valuable and rare proof set had all remained together.

Another 1936 proof set was auctioned in January 2017 at $17,625. The five values were also graded by NGC individually between PR66 (4 of the five values) and PR68 for the nickel.

Also, NGC individually graded another lot of 1936 proof set in April 2012 that sold for $14,950 with grades between PR65 and PR67.

In this ranking of auctions of 1936, the first one graded by PCGS that we found is the one auctioned in January 2004 that sold for $13,800 with the five individually graded values between PR65 and PR66 (Source).

We continue with the NGC gradings for a 1936 proof set sold for $13,225 in 2010 with gradings of the five values between PR65 and PR67.

In November 2014, HA lot number 4237, graded by NGC in the individual long 5-value case with gradations from PR64 to PR67, was auctioned for $9,987.50. As a curiosity, it is rare to see at auction this type of long encapsulation with all five values together and graduations on the label.

We have left out showing more values of the 1936 proof set so as not to make the information repetitive, as this is a very common proof set in sales and auctions.
We will only say that this is a proof set that continues to appear in auctions at lower prices than those shown above, depending on the grades received for the group of its five values: PR67, PR66, PR65,…

2. 1939 Proof Set – $10,800

According to PCGS, the 1939 proof set is valued at $1,300, but in July of 2022, Heritage sold one for $10,800. This price gives us a good idea of the current valuations and demand for early sets.

These are the five values graded by NGC in individual capsules, with correlative numbers and grades between PR65 and PR68+ (this final grade corresponds to the half dollar).

3. 1937 Proof Set – $10,200

The second date of presentation of the proof sets is also highly sought after and in demand. Recently in October 2021, a 1937 proof set of 5 individually graded values by PCGS between PR65 and PR68 went for $10,200 (Source).
In September 2015, a 1937 proof set with NGC gradations somewhat lower than the previous example (between PR66 and PR67) fetched $8,225.

4. 1990 Proof Set no “S” cent – $8,265

Several things strike us about this set sold for $8,265 in November 2004. It is the original set, so all five values are together and UNCERTIFIED. However, the auction house indeed gives the 1 cent denomination a PR69 Red Depp Cameo, being the star of the set as it is the 1 cent without the San Francisco “S” mint mark, and the rest of the values PR69 Deep Cameo.

The key to the valuation of this set is the 1C without mintmark. The reason is that the 1990-S proof set with the mintmarks values has a much lower valuation: it can be obtained for $20.
It appears that the Philadelphia mint, who made the dies for the San Francisco mint, forgot to include the mintmark “S” punch on the obverse of the 1C value. Subsequently, the Mint produced 3,500 units of the 1C with this error. How many of them ended up in the 1990 proof set is still being determined (Source).

5. 1968 Proof Set no “S” Roosevelt Dime – $6,325

1968 was the first year that the San Francisco Mint made sets, always with dies manufactured at the Philadelphia mint.
In October 2001, this rare 1968 proof set was auctioned with the famous Roosevelt Dime error without the hard-to-find San Francisco “S” mint mark. All five values were graded PR66 and priced at $6,325.

List of Proof sets by year

As you can see in this list, the value of the proof set depends on the year of issue and its state of preservation. Although most of them are less than 200 dollars, other series much more sought after by collectors reach much higher prices.

Remember that if you want to sell your proof set to a coin dealer, the price they will offer you will vary depending on the collection condition, the rarity, and the demand in the market.

As additional information, in addition to numismatic stores, auction houses, internet portals, and others, today you can purchase many years of proof sets on the United States Mint website.

1965 Uncirculated coin set value

A 1965-proof coin set is generally valued between $10 and $20. This set includes five coins:

• A Kennedy half dollar
• A Washington quarter
• A Roosevelt dime
• A Jefferson nickel
• A Lincoln cent

All the coins in the set are struck in a specially-made proof finish, giving them a highly reflective, mirror-like surface. It’s worth noting that the Kennedy half dollar in the 1965 proof set was the first year of issue for this coin, which was introduced following the assassination of President John F. Kennedy in 1963. This could make the 1965 proof set more desirable to collectors interested in commemorating this historic event.

However, some of them can reach much higher price. For example, a 1965 Special Mint Set MS certified by NGC in a MS67 grade, which achieved $99.95,  the highest value gained in 09/2021 at eBay (reference).
