Two Dimes Same Markings Differnt Mints

@chromemaster, first welcome to CCF. Second, I think that you are talking about the somewhat circular arcs of damage across the portrait. While I agree that it is a coincidence to find too with similar scrapes like that, it is perhaps even more impressive that you remembered about the first one when you found the second one these few years later. There is no numismatic value beyond face value for either dime, but certainly save them if you want as they seem to be "brothers".

Great eyes. Keep looking. We have folks report neat finds here almost every day.

@CM, we would love to see more of your interesting coins. Best practice is to start a new thread for each coin and include the date and denomination in your title (makes for easier researching down the road).

I was thinking that the marks from rolling machines seem to be closer to the edge, but this is as good of an explanation as any.

Probably from a coin rolling machine as mentioned. It is amazing to have them both hit in the same area though.

In the "Search Coin Community" area on the upper left corner of CCF type "coin rolling machine". You'll see plenty of results that look like your coin.
