Well that is the chance everyone who really needs it have to deal with. I for one Not all the coins or sets really need them. If I didn't get it, then I guess I can live without them, but if you can't then you have to pay or wait til when they aren't hot anymore.
I neglected to mention that if there is no "mintage limit" as such indicated for any particular item, that is because that particular "product" with its attendant "product limit" consists of one or more otherwise accounted-for, i.e., separately listed item(s) with their own "mintage limits".
