3rd Millenium US Coins Type Set with Major Varieties, Circulation Strikes and Proof, by Mint (2001-3000)

Type Set including major varieties in circulation strikes and proofs, and for each Mint. In progress, 115 of 140 Coins.

US Coins only, Commems, Eagles, miscellaneous gold is too much for my pockets. But what is a US coin? Does the 50c Kennedy 2014 W gold count? Does that mean the 2016 W 100th centennial 10c, 25c and 50c gold count? Which means the Peace and Morgans count, right? If none of those should count, then maybe Innovation Dollars shouldn't count? The Sacagawea 2016 S Enhanced and Sacagawea 2017 S Enhanced are possibly the same Variety(?) or maybe they are struck differently or something, I need to research that, but for now I'm justifying including them because of the variety of the US Mint Set- "Enhanced Uncirculated Set" vs. "Coin & Currency".

It's probably subjective and down to what I can reasonably afford. I wish I could reasonably afford this type set including everything from the US Mint. I could afford and did find a 2001 P Sac$ Experimental Rinse "error", so, I'm subjectively including it.
