I sell Kennedy half dollar coins on Ebay in lots of 100. I have different varieties such as promise to include at least 25 different years/mint marks or 30 different years/mint marks or 40 etc. What I mean by that is if one wins the listing will include at least 25 different coins not 25 different years but 25 different years/mint marks such as a 1971 and 1971D. That would count as 2 of the 25. How do I word my description so buyers understand that? Thanks!
