My experience is that large lots bought from Roecy are what are termed "floor sweepings" and in their case the term may well be literal. I was looking for some US 20th Century cancels and bought a large lot from them, and when it arrived the covers were stained, musty and mildewed. The scarce items I needed were there and in good shape so I did not return the lot, but I did make clear to the seller that the condition of the items ranged from tolerable to complete garbage. He expressed the kind of surprise that suggested he knew all along what he was doing.
IMO Roecy caters to bottom feeders, and whenever he promises valuable material to a client he is in over his head and when he can't deliver dithers and stalls rather than makes prompt refunds.
Caveat emptor.
