1961 Topps 183 Andre Rodgers

I've always wondered what Mr. Rodgers is looking at... Anyways, blue splotch on forehead and a streaky blue mark in his jersey, directly above team box. This card is very tough, I've only seen one other, although I stopped looking for too long after finding this one.

The splotch on his neck is a pack or gum stain, not a mark

And here's yet another 1961 with some yellow difficulty. Note the break in the frame in the lower right by the team name box, that is filled in with yellow. 10% or so of Valo's seem to have this issue

Hope I haven't spammed this thread too much! 205 Bill Pierce, with green splotch above team name box. I think this is also somewhere in the 5-10% range

The 1967 McCormick card, the common one with the traded line, has a recurring defect with the cartoon. Note the white ink for the cartoon box is not aligned right. This is something like 25-40% of the cards, the rest are correctly aligned.

1961 Topps 259 Reds Team - with a misshapen bottom right corner, or a correct one. This variant is a really easy one

#262 Tony Curry - with blue dot on bat knob. Very easy print defect

270 Bob Friend comes with or without a red dot on his pitching arm. The red pixel version is rare.

274 Gary Bell can sometimes be found with a blue spot in the grass above the team name box.

Not sure how tough this one is, but its not common.

292 Jim Baumer - another tough yellow splotch defect, this one above the team name

289 Ray Moore - a tough one, this one with a blue splotch in a white outline by his face. Most cards don't have this defect.
