Found six Proof cents, all in its original mint packing, showing what are possible errors which cannot identify as I am new on this.
1970 observe shows a "delamination" in theword UNITED
1986 reverse shows some type of "bubbles"
1989 observe shows a "crisped" surface
1990 reverse shows a weel defined decoloration
2006 observe shows some sort of a high releif next to the date.

Will appreciate commets/opinions

1970 could be a carbon spot. (these happened on the copper planchets) Not a plus for the coin. Probably the reason it was spent.
The rough texture is the result of a poor rinse technique. The zinc dust was not rinsed off before the plating happened.
1990 the seal on the proof set was cut and the finish turned colors.
2006 just a gas bubble under the plating.

#1 shows damage, #2 and #3 show plating issues, #4 shows a stain of some type, and #5 shows a spot from damage as well. No error, here at all.
