The 1838-O half dollar is a genuine rarity, with only 20 pieces struck and the fate, 170 years after striking, of just about a dozen known pieces in existence leaves some unaccounted for. I’ve liked this coin for many years and made it a centerpiece of my new book that Krause is publishing in July, “Profitable Coin Collecting.”

More than 50 public auction sales of this coin are of record, some over a hundred years ago. The Mickley sale in 1867 by Woodward saw the coin offered as Lot 1782 and the selling price of $2.75. The same coin was acquired by J. P. Clemens and when Edward Coogan sold his collection in 1878. Lot 159 contained the same coin and brought $15.

Frossard sold his own collection Oct. 2, 1884 and Lot 400 in that sale featured an 1838 New Orleans half dollar which brought the “enormous” price of $63 only to find an early case of economic recession in the coin field so that by the time Lorin Parmalee sold his collection in 1890, the coin stepped back to $23.50.

Thomas Elder sold the Wilson collection in October 1908, and Lot 346 featured the very same 1838-O half dollar. It resounded to a $570 mark. In the span of 40 years, the coin rose in value from $2.75 to almost $600 – weekly wages in the United States at the time averaged about $6.

In the 1950s, the Anderson-Dupont sale by Stacks yielded a $3,500 price realized for an impaired proof specimen. That coin would be resold nine times in the succeeding half century and form the basis of the mystery that has existed for almost 20 years.

The unknown answer: an August 1989 sale as Lot 202. What was the price realized?
