Customer rolled, handrolled, or machine rolled. With a box of machine rolled dimes, one can average 1-2 rosies. However, you have to search through $250 worth. So if you only have $50 to buy rolls of dimes, then your likelihood of finding silver out of machine rolls is slim. Searching customer rolled/handrolled dimes, you have a better chance of stumbling upon the dream roll (many silver to near solid roll). I've never heard of anyone scoring a solid roll of silver dimes by searching machine rolls (at least not in the past 30 years).
