Tom,

Believe their Copper Strikes issues were,in 2000,or 2001. Used to go to Biloxi 2 or 3 times a year,and was able to buy strikes from the Imperial Cage. Bought three sets,& all were Copper rims. Kept one set,& traded the others. On my next trip back,I requested more,but it was a one time deal. Have never seen another set offered since yours. Do think they are a rare issue.
