Here is an oddball. Believed to be a 1943 Mercury uniface reverse dime struck upon the planchet metal used for the 1944 1/2 Bolivar coin. Weighs between 2.2- 2.3 grams. Absolutely no reverse detail. Completely blank. Prototype or error?
Slightly golden in color. and EX-AU details.
Somebody decided to improve upon the coin by improperly cleaning it!
Appears to be .835 Silver and .165 copper.
Regardles, I seek commentary. Anything known about these errors? Help if you can. Thank you Gusp
