Floortrader: I agree with you. If I don't know the seller then I would need to view the material in person before buying it. Scans can be easily manipulated, enhanced or edited.
As the UK remains in lockdown (essential journeys only and viewing a collection doesn't count even if I were to keep 6 feet away from the seller and sit in their backyard) I recently suggested to two UK collectors of USA to mail their collections to me, at my expense and insurance as they had very few details about value (no receipts, no certificates, no idea of which dealers or auction houses they bought from) but I'm still waiting. I suspect both collections are what the Brits call "schoolboy albums".
On the other hand, a collector in Europe who I've spent more than $50K with over the past 20 years had some more material for sale. He emailed me scans and descriptions and we agreed that half of the material was better-suited to a dealer friend of mine Stateside and that's on its way via FedEx. Both the buyer and seller trust me and I'm sure they'll both be happy with the outcome. The material which I'm buying is on its way via Registered Mail and I'll send a bank transfer same-day as received.
