Thanks to all of You guys wich reply to this post.
Some details for You to know:
This coin have been stored away for many decades on a safe box with many others. In the safe box i found just 3 american coins the half dol from 1867, a one dime from 1883 and a trime (3 cents), from 1861.
I just opened they safe box to days ago.
I didnt clean any coin, and the safebox belonged to My great grandfather.
I live in Chile, so i don't know to much about american coins and the marks on then aswell.
In the safe i found many Chilean old coins, and some others from other places around the world.
Thanks again.
