Hi Matt,

If the tokens have Joe Mackie's Star on them they are probably the 1965 copper token made by Michigan Tool Engineering. There was not a date on the 1965 token and ther may be a small mintmark (TME) on the token. Would be interested in only one in the best condition of those you found after you determine value. I have chips or other tokens for trade if you wish also. LMK

Thanks,
Roy
