It's an eBay seller who appears to have an incredible inventory of graded cards up for sale. If you click on the individual cards, the description references a stock liquidation from someone who has closed a pawnshop business. They say they are soliciting offers on the cards.
But if you click on the seller's feedback, it's all nuts, bolts, screws, etc. as their name would suggest. The card listings say they ship from New Orleans, but the seller is based in the UK.
And a bunch of the card photos have the Probstein watermark. Any idea what might be going on here? Any chance these are legit listings?
