Proof-Only Gold Coins
By Doug Winter – RareGoldCoins.com
The presence of a number of important Type Three Proof Liberty Head double eagles in the upcoming 2011 FUN auction got me to thinking about . What are these coins, why are they important and do they deserve the market premiums they enjoy?
A Proof-only coin is an issue that exists only in a Proof-only format where business strikes could have been produced as well. These coins exist in a variety of denominations but for this blog, we’ll focus on the ones in various United States gold series.
Some of the most famous Proof-only gold coins are the double eagles from 1883, 1884 and 1887. The mintage figures for these dates are 92, 71 and 121 respectively. I believe that there are around twenty 1883 double eagles known, maybe fifteen 1884’s and as many as thirty to thirty five 1887’s.
There are two ways to look at these coins. The commonly accepted way is to consider them solely as a date. In other words, even though there are many Proof double eagles that are rarer than these three, there are no other Type Threes that compare to the 1883 and 1884 in terms of the total number known. If a date collector wants to buy an 1883 for his set of Type Three double eagle he has to buy a Proof. This is different than a rare date like the 1881 or the 1882 that exists in dual formats; i.e., as business strikes and Proofs, and thus presents the collector with two options.
Collectors who are new to double eagles might balk at having to pay $150,000-200,000 for a nice 1883 double eagle when they can purchase a Proof of comparable rarity from this era for half as much–or less. Why, they wonder, does a Proof-only issue get such a high premium?
The mistake that they are making is to compare the 1883 to, say, an 1880. They need to look at the rarity of the 1883 on an absolute level. The 1883, from the standpoint of total number known, is even rarer than such celebrated issues as the 1854-O and the 1856-O; two issues that now sell for $300,000-500,000. If the Type Three series were to ever become as popular with date collectors as the Type One series currently is, the current prices for Proof-only issues such as the 1883, 1884 and 1887 could double or triple.

This sale will occur almost exactly two months after B&M auctioned the first part of the Malibu Collection, in Baltimore. In
Some may wonder why I am focusing on collections rather than on the most expensive coins in these two auctions. I write about a wide variety of coins, not just expensive ones. For discussions of modestly priced coins, please see some of my recent columns:
As best as I can tell, all of the pre-1916 Proofs in the Carson collection are
