This unbelievable Mint Error was the feature story for the first issue of Mint Error News Magazine. It is a 1998 Chile 10 Pesos double struck on the actual feeder finger!! This is one of the most incredible and spectacular Major Mint Errors that has ever surfaced. After reading about the U.S. Coins struck on feeder finger tips, one can appreciate this piece even more because it is completely intact and did not break off. Bill Snyder of worlderrors.com e-mailed me after visiting minterrornews.com. He is a collector of world errors and read about the group of U.S. Coins struck on feeder finger tips. He asked me if we would feature this amazing feeder finger error on the website. After several conversations, I finally convinced Bill to part with his prized posession and was lucky enough to purchase it on the spot. This 10 Pesos design was struck at the Santiago Mint in Chile from 1990 thru 1998. A regular piece has a composition of Nickel/Brass.
