You might want to check on eBay of course. I think you can set your eBay up to search for new listings. Once you put the type chips that was stolen you can then see if the same seller has more of them for sale at the same time. Its a long shot but you never know. Also check your local pawn shops and coin stores. Please give us more info and maybe we can look out for them on eBay for you. I know its very upsetting to have something stolen from you. Please keep us posted.
Kind Regards
