I have seen a lot of conversation regarding the 1971 S Eisenhower Proof with and without the Peg leg R over the bust. I have examples of both varieties in Proof 70 Cameo. One is in the Mint packaging the other was purchased from a online dealer which has the straight peg leg with NO Fading. The mint package variety has the Serif on it the other does not...I will try to post photos of both in a short time for comment
