2017, 20, 21 lincoln obv. clash, line back of lincoln's profile (left facing coin) first is 2021..just the left side, one line from shield...au-58..no wear, but fingerprints (not mine) then comes the 2020 clash marks both sides of lincoln bust, one on left, two on right, same grading, def unc, but fingerprints..ngc and pcgs may not care about them, but i drop it to au if fingerprinted...2017=p both sides, though faint on rt side..scratch on rev, so au-details grade au-55 very inexpensive though 4.99 ea and 1.36 shipping...
the last 4 pics here: i have purchased maybe 7 or so coins from this vendor, and currently bidding on 6 more..he sells mostly clashes and his starting prices are moderate...
