Untraceable, could only match 10 keys. Keys went to the beams ninja, so the key histories on the buyer’s end would have to match with the previous owner of the ninja.

Sales at:

14 (3x)

15 (2x)

15 re-sold for slightly less than 15, but still rounds to 15. Not going to exclude either. The buyer’s purchase is still valid, and the difference it re-sold for is very minimal.

Taking 14-15.
