The tumbler did good work. But did you know that tumbling coin reduce its value if it was a collectible coin? Before tumbling them, check their year first and see if they are of value. Collectible coins are worth more with all the dirt on them and leave the cleaning to the collector. Don’t mix silver and copper in a tumbler, copper will mar the silver. Best to only tumble same type of metal together.
Definitely clean looking. But that is a very good (bad) way to wear down a coin. I guess it was not really an issue for most of them, but there is a couple of coins in there that you should not have done that to.
