I dug two aluminum pop bottle caps ringing in at 22 and that token was the third 22 I almost just passed on . Had to do a double take on that when it came up . That is a 1940s japan hedge hog play dime . I hear they are rare but I have found four or five in the last three or four years so not that rare I guess . People try and sell those for $40 on ebay once in a while . Super thin and has a light stamp .
