Untraceable, 5 keys match (buyer’s end), some matching with the previous owner of the unusual the seller bought after this trade.

Sales at:

15

30

Given the marketplace sale for slightly cheaper than 30, and the potential purchase at 15 keys (#3), I’m going to exclude 30.

Sale at 15 is over a month old, will be fine to use.

Taking 15 flat.
