“Then arose some discussion over the silver piece, which the proprietor of the store stated amounted only to the value of twenty cents, but which the before-mentioned Davis had apparently fancied was a quarter. The instant Davis departed I hurried to Mr. Welcome and asked the privilege of examining that piece of money, which he kindly showed me. The moment my eagle eye fell upon it I knew it was a coin on which there was a premium, as it bore the date of 1878. This piece of money I secured from Mr. Welcome, giving him fifty cents for it, and it is here among the exhibits as evidence in this case. There is upon it a mutilation, a tiny cross cut or scratched by some sharp instrument.
