Indian / Buffalo Silver Round Error

It isn't a coin. It is a silver round. Looks they wanted to make it look like an error coin.

Coop is right. Because there is no government control over the private mints that strike these rounds, they can play all day long creating weird and interesting "errors". Any error made on purpose isn't an error - it's a curiosity.

Another thing is that because these pieces are undated, they could have been made any year.

I cannot answer the question at hand (about the reeding), but I do hope you didn't pay some sort of premium for this piece. It's worth two ounces of silver plus a small fee for the curiosity.

Nice photos, by the way.

These are made by the same process as coins and the possibilty of errors do occur (not on purpose) on rounds the same as they do on coins.

The broadstrike for example is the very same as the broadstrike on a coin, in both cases the collar is out of position allowing the plachet to expand when hit. Double and triple strikes have the same result.

Depending on the type of error the premium on these is pretty good, here are pictures that I found online to use as a reference of a few more errors for your view..

Bottom line.....Beauty is in the eye of the beholder..
