I was looking in a old shed behind my parents house. The house was built in the 1850's. I found a bunch of coins. They were in a dried out leather bag hanging up in the corner of the shed. There are about 20 mercury dimes. I noticed they were each wrapped separately in brown paper. Are those things safe? Also 10 Liberty Walking Half Dollars. Most of the coins are pre 1940's. Some from 1890's. There was one 1853 half dime. I left them with my parents. They had no clue they were there or they just forgot. I will inherited them one day.
