Thanks @Beardigger I have one and really don't want to start another set of something. I do appreciate the chance to build my collection.
Yikes. Depends on what you want to do. 1996W dime from mint set. 2014W Kennedy half proof from 50th anniversary set. 2015W proof dime from March of dimes set. 2015W Sac RP from NA coin and currency set. 2019W cents 3 types 2019W quarters 2020W nickels 2 types 2020W quarters I'm not sure if this is all, fairly sure though... But I'm not going to get into gold or silver bullion coins with Ws. You could just do business strikes. Or you could do proofs and business. Or just do "circulation" coins which limits it to the quarters. Gotta draw the line somewhere though because it gets costly I think especially if you go into bullion.
