I don't know about the rest of you but as a kid i always heard about these near impossible to put together "sets" of a just a few coins (the 3 buffalo's on hills comes to mind though i don't remember the dates lol) that could make you "rich" if you found them.. of course it usualy came down to 1 specific coin in the sets... one set i've bought with this in mind are my 3 2019 "W" cents... now the question is should i add the p d and s as well "a full date set" of 2019 cents... (bringing to total to 9 coins the others lacking the rev proof)... IDK but I think the 3 Ws stand well by themselves as a set What do you think..? anyone else have small sets they building?
I think it cool you sent all 3 out for grading. Thanks for sharing saw this link ungraded FYI2019 W UNC PROOF REVERSE PROOF LINCOLN PENNIES SET OF THREE COINS | eBay
If you're a completist (or slightly OCD like me) you could add the PDS but I don't think it would add much value or interest to the 3 special issues you've already got. Just my 2 cents (no pun intended)
I think the 3 W cents stand alone. I am guilty of buying all the eligible mint products that year just to get these! But, the PDS issues would just add to the set and would be far cheaper to obtain than the W ones, so go for it!
