While checking which Rizzuto I have (I'm sure I've missed or don't recall posts among the 2,800+), I remembered the Jackie defects I don't think have been mentioned before.
There are multiple recurring minor defects on the back of 1954 Topps #10 Jackie Robinson. My copy here has a white triangle next to his 12 home runs, a white slash next to P.O., and the F. Avg. label is partially obscured.
Here's one from COMC, with with the P of P.O. partially obscured, and the F. Avg. incomplete. Notice his 136 games is also partially obscured.
Third, a copy from COMC with the F. Avg. complete to show it's not all cards that come this way.
There are at minimum several different total combinations of recurring defects, some easy and some rare-very rare.
Defects are a lot more fun on cheap commons
