I have a older MVP Ion, All Black, No Stamp Still says Maple Valley Plastic on the inside.
2nd run looks to be in pretty rough condition. I know some of the black opaque protons were suppose to be rare but found many sold/threads/posts etc with people who have them as well. Was eyeing a special stamped 10/10 2nd run black for offer of $50 but didn't accept and sold a few 2nd runs for 20-30 given condition.
Someone will buy it for sure but not really worth a ton of $.
