actually my mind is lost. Im not thinking 2015. there was an early issue that they didn't make a lot of and was $5k out of the gate... what year what that one. The 2015 was a recent find that Philly minted... they called them something else before.... I break them out of the holders anyway and put them in my dansco albums. IMO a grade of 69 and 70 is no difference. Ive always wondered how they can find any difference in the 2... I guess thats why im not a grader... lol agree with the chips being graded. the chips ive seen graded and called mint are far from it in most cases... lMK if you know what the rare one is?
