Well, distinction between Signature and Sunday auctions was new to me. And as you said, terms aren't clearly defined, and the expert has the last word. I doubt there is something in HA clearly saying that minimum consignment value for both auctions apply; if you find it, share it.
I initially contacted them because I have two posters I bought some years ago which sold pretty well in their past Sunday auction; since I posted a link to past Sunday auctions in my email, my question was for the Sunday auctions not the Signature ones.
"
I have a poster I would like to consign. It is the exact same one that one you sold recently at your Movie Poster auctions [link to Sunday auctions here] but in Very Good condition. Kindly let me know if you would be ready to accept this poster in your upcoming movie posters auctions."
I got the Ebay-$5000-threshold reply, so I replied the following:
"
Thank you for your answer. Ebay is a good place but considering results for this poster at HA, your Sunday auctions is the best place to sell it."
And added:
"
Just last one question, what if I have same poster in multiples (apx 20 pcs [...]), would you be ready to accept the consignment and sell them at Sunday auctions over a one- or two-years span."
Fact is that I found someone with stock of posters which sold for $200+ at HA, that's a $100+ markup. I was hoping the few I have would be accepted for Sunday auctions, it was not; so I try the bulk approach to meet their threshold, but in vain.
Conclusion for me, too bad ! I have poster I want to consign to HA weekly auctions but can't.
Conclusion for this topic/thread, as said earlier, this thread sounds like consigning at HA is a piece of cake, it is not. If you do, you should consider yourself lucky
Add to this different date, different condition, etc., clearly we are comparing apples and oranges.
