HOW TO PRICE VERY RARE COINS

If you collect very rare or finest known coins, figuring out what to pay for an item that you need for your collection can be difficult. Here is a real-life example of how I came up with what I believe to be an accurate value for a one-of-a-kind coin.
The coin that we are going to use as our Coin Pricing Lab Experiment is the Finest Known 1860-C half eagle; an item that my firm recently handled.
When analyzing any complicated, rare issue, there are at least four things that I give major consideration to:
1. Establishing rarity
2. Determining comparables
3. Gauging the depth of the market
4. How nice is the coin for the grade and for the issue
So let’s take the scenario that I am bidding on this 1860-C half eagle at auction (as opposed to selling it by private treaty) and assisting Collector X. The first thing that I am going to help him with is a basic understanding of the rarity of the issue.
According to the soon-to-be-released third edition of my book on Charlotte gold coinage, the 1860-C half eagle is a moderately scarce issue with an estimated 125-150 pieces known. My best estimate is that there are seven to eight properly graded Uncirculated examples with one in MS64 (the present example) as well as at least two or three in MS63. I would suggest to Collector X that he remember that with as many as three known in MS63, the chances are pretty good that at least one will magically transform into a second MS64 in the future. And should this happen—and his coin is no longer “population 1 with none better”– it will lose value.
Most collectors eventually check out the PCGS and NGC population reports. As of April 2008, PCGS had graded a total of eleven 1860-C half eagles in Uncirculated while NGC had graded twenty-five (!) in Uncirculated for a combined total of thirty-six. Now, I would be quick to tell this collector that these figures are dramatically inflated by resubmissions and that virtually every 1860-C half eagle that I have seen in a PCGS or NGC slab below MS62 is debatable about whether or not it truly is Uncirculated. But there is no denying the fact that there are enough purported Uncirculated 1860-C half eagles out there to make this MS64 lose a bit of its luster. It is a scarce coin but not one that could be called a fundamental rarity as it is readily obtainable in circulated grades and even available in the lower Uncirculated grades from time to time.

An important technological advance was the introduction of the steam press in 1836. Coins were now able to be struck using a close collar which allowed for a thicker edge and a more precise diameter and sophisticated designs. It also meant that the quaint, “folk art” designs of John Reich were to be replaced with more modern, technologically savvy renderings.
What is an Eagle? According to my 1975 Webster’s New Collegiate Dictionary, it is a diurnal bird of prey noted for its strength, size, gracefulness, keenness of vision and powers of flight; the silver insignia of rank for an Army colonel or a Navy captain; or a member of the Fraternal Order of Eagles. In golf, it is the completion of a hole in two strokes less than par. In gold, it is a coin!
However, either antiquated edition might as well have been set in type by Gutenberg, as they both predate the current American Eagle one ounce gold coin first struck in 1986 with a face value of $50. This new coin left us with two different legal tender “Eagles” of different weights, sizes, finenesses (usually) and denominations, and hardly a day goes by at Berk’s that we do not have to explain the difference to a would-be customer.
