1962 Proof Cent With Anomaly. Gouge? Clash? Hubbed In Debris?

Added this odd little coin to a larger order. There is an interesting raised object below Lincoln's ear. The seller couldn't definitively classify the raised anomaly, but the speculation was die clash.

I see no other evidence of a clash on either coin face. To me, this resembles the hubbed in debris we discussed a couple weeks ago on a pair of 1964 proof nickels. It seems too knobby and asymmetrical to be a simple gouge. Anyone else have observations on what might have caused this anomaly? It is a porcupine to photograph because it's a proof, my little magnifier was overwhelmed with the glare, so I had to use a macro lens.
