If what OP is referring to is across top of motto, that is
Die Deterioration, and a bit of
Grease Fill possibly. The stretching towards outer rim is classic deterioration, metals move outwards when dies wear. The TRUST shows this effect and angular "shaving", (edges are too sharp) and is not hub-doubling. Coin is in rough shape too, many hits all over,, note MM "S", "LIBERTY" and date(field too). Pix could be better, but 90% of true doubled dies are quite obvious because there is an increase of the size of original details, only increase here is
Die Deterioration.
