Not an auction, but open it first
Popsike is not a saleroom and sells nothing. It is an archive of completed auction results — tens of millions of them, largely from eBay, running back to 2004 — searchable by artist and title, with a blues category. A hammer price is evidence; an asking price is an opinion. Check the evidence before you set a limit, and check it again when the same record appears twice in a year.
