I found my mercury dime dupes in a bowl in the garage. I have 562 coins.

I don't keep up on prices. However, I checked the last auction to close on ebay for junk mercury dimes (mine may be better). 50 went for $147.50 + shipping. Firing up the old calculator I calculate 562 should go for $1657.9

Therefore, I would sell for $1600 + shipping or best offer. Email me if interested.
