I was wondering if this is some form of DDO or DDR? It looks different then several other 1968 pennies I have...
DDO = Doubled Die Obverse DDR = Doubled Die Reverse So you don't have a DDR. Looks like machine doubling which isn't considered an error.
They are just high relief coins. And a full photo of the coin front and back would help without blue and dark picture. And let the phon focus a little more.
