3.73 grams versus normal 3.1 grams (20% too heavy!). PCGS said error but could instead be a pattern or foreign planchet. Also looks off metal but PCGS did not test it. 

Only thick/heavy specimen of this date that we could trace. Similar to overweight 1944 version (dozens known) that Pollock calls pattern P-2078, which have auctioned for up to $3,000 in MS64. But unlike the 1944, this 1936 coin also looks off metal. 

Medlar's flip included.

All coin planchets are punched out of metal sheets that were "rolled" into a particular thickness, so PCGS's description is unnecessary. There is no way to know whether this coin was deliberately or accidentally made thicker and heavier than normal (pattern versus error versus foreign planchet). Regardless, this is the only thick planchet 1936 cent that we could trace. 

Unusual looking oddity sure to be the centerpiece of almost any coin collection. Impress your friends and even your mother-in-law.
