I had an old timer dealer come to our table and hang out for a while. He had a box of old cigarette packs. There were about 20 of them. He knows I have collected them so was offering them to me. He said they were a consignment of his and he was asking $7000 for all of them. He said they were in near mint shape. I would have called them Poor - VG.
After looking at them fairly carefully I told him I didn't think we would be close so I will just pass. He pressed me quite hard for valuations. (I think he was either clueless or foolish, one of the two). I told him retail on the lot was about $2500 and I am a buyer at half of that. He thanked me for my opinion. Had I bought at his asking price it might have counted as theft?
