That looks like its marker or paint of some kind.. Have you tried cleaning them to see if you can remove the RED, I don't think the red is suppose to be there.
I remember seeing those chips for sale when they came up, and wondering about the pink/red spots. I completely agree with chipjoker, I doubt the spots were red originally. I've cleaned thousands of dirty Paulson chips, by hand or by ultrasonic, either with TSP, Oxyclean, or dish detergent, and sometimes additional cleaning using Goo Gone for sticky substances, or very long soaks in alcohol (with intermittent scrubbing) for ink stains. But frankly, I've never really seen anything like the red color above.
Any idea of what I could use to see if the Red will come off?? I don't want to destroy the Hot Stamps.
Cleaned and Oiled them all.
Maybe find one chip that has a not-so-great stamp or nick/scratch/flea bite
I'll second this, take one chip (or multiple test chips) and use them to test cleaning methods. If you haven't tried TSP or Oxyclean, you might want to try these out to see if either of them make a dent in the red removal. But too long or too strong of a cleaner might remove hotstamp foil or fade the chips colors, so test first.
Something else to test, after they are oiled, if you rub the face of an oiled chip on a white towel, does any red color come off?
If the red is an ink like a sharpie marker, soak them in rubbing alcohol for several days. Yes, days. I used a soup bowl, but something with a lid like a mason jar would work, and should keep the alcohol from evaporating. I don't have any pics, but this worked to remove sharpie on a couple Paulson chips. Every day or so, I'd have to do some additional manual scrubbing with a toothbrush, but slowly, the ink dissolved and came off. Alcohol shouldn't damage the chip clay, but I don't how it'll affect hotstamps - test.
