Off center inlays or Paulson's penchant for scratches don't interest me. But I think a printing error like yours, which the manufacturer works agressively to keep out of the market, is very interesting.

Here is a chip I found last year, in a stack of brand new chips. The one on the left is the normal chip. The one on the right is very badly printed. I looked at nearly 100, and all the others were quite normal.
