1972 did indeed have Peglegs from the Denver Mint but the premiums associated with them is relatively small until you get into the higher grades which is typical for IKE's. Most of the Denver Issues have Pegleg coins.
Good good to know. Now all I need to do is figure out for sure if this one qualifies and how to figure out a grade. Btw I have like 5 others that I think are peg legs as well.
