These account for nearly 15% of 1970 mint sets. The small date is 10% and there's a lot of demand for them. U think $15 is highly optimistic. I've seen thenm advertised this high but I'd suggest that for just alittle more you can get an entire 1970 mint set. They aren't picked over for the OMM. I've got several rolls of these that I've picked up over the years so would love to see them sell at $15.
