Watch List notes:

UNITED STATES:1953, silvered copper medal, H&K-509b, NGC graded MS65, "So-Called Dollar", Louisiana Purchase Sesquicentennial, COMMEMORATING THE SESQUICENTENNIAL OF THE LOUISIANA PURCHASE around rim, knight on horseback; to upper right 1803 / 1953, MFGD. FOR & DISTD. BY / ODDEHON / ST. LOUIS, MO below horse // CELEBRATING THE 150TH ANNIVERSARY / OF THE LOUISIANA PURCHASE, map of North America showing map of the Louisiana Purchase, RR, ex Jeff Shevlin Collection. Medal privately issued by Otto Oddehon of St. Louis, Missouri and struck by Adams Co. Apparently there was talk at one time of staging another World's Fair in 1953, but nothing developed. Oddehon "decided the event merited at least a privately struck medal of some kind" and unable to secure any official cooperation went ahead with it himself as a "patriotic gesture." The issue was limited to 5,000 pieces in pure copper and sold for 50 cents at that time.

Estimate: 200-300 USD
