Just wondering if a second coin has struck the revers on my 1961? penny? Any ideas on how this could happen? Reverse is really mushy, best picture I could get of the "impression effigy".

Yes, it looks like it was struck through a late-stage die cap.

The 'orange peel' texture is a good indication, as is the fully formed rim.

Thanks guy's. I have seen many die caps but never an example that was struck the second time with the hammer die. My question is how did the Queens effigy end up on the reverse of the coin?

You are seeing two things here:

1. The pull of metal into the obverse, which produces the 'ghost' of the Queen on the reverse. You can also see 'ghost images' on normally struck coins and split planchet errors.

Check out the split planchet errors here too for some good ghosts: http://goccf.com/t/330437

2. The cap on the hammer (reverse) die is late stage, which means it has been pounded quite thin, and you are also seeing the design transfer of the hammer die through the cap onto your coin. As the cap on the die gets thinner and thinner, more design elements come through.

Example here: http://goccf.com/t/320547

Plus, the die cap can wrinkle and break into fragments, which looks like might be happening to your coin.

Thanks SPP as always. That seems to make sense. The only other way to see if there is an actual impression is to use digital calipers but I only have the flat ones. Good hunting.
