My Borland-made "Mr. Chips" personal black chip goes back way before Jerry's. In fact, I used to give them away to coin dealers at ANA conventions when I collected Bust Half Dollars during the 1980's instead of a cheap business card. I often found that business cards tend to get thrown away, but the personal chips would wind up in a cash drawer or someplace else and served as an excellent way for coin dealers to remember me from convention to convention each year.
