Really never found anything good in uncleaned lots, but decided to take a chance on this one. One thing, they aren't small coins...
Be careful cleaning them. Some need to be left alone. The one below I started to clean only to fine out that it was a relatively scare coin. The dark shiny areas are actually part of the detail. Perhaps all that is left. This one is better described in the attached: https://www.cointalk.com/threads/what-is-this.358206/
