I don't think i posted this before and was wondering what it was .
HUB is on both sides.I think it is 21 mm just a little smaller than a nickel and i think it is brass with a silver coating not sure what but not silver.
Roger--looks like one of the many "Amusement Tokens of the Minneapolis St. Paul Area" tokens. I don't find this particular one listed, but it certainly has the look. There was a Hub Bar at 194 E. 7th in Minneapolis, but the token shown from there is different.
