I'm selling my collection. I have painstakingly logged every single card in my collection, which might not sound like much to most of you guys but it was a lot of time. :) I'll gladly provide the (3MB) Excel workbook to any buyers who want it. (for the fellow Excel-geeks like me, it's in table-form with pivots).
As far as how much: The prices in TCDB can get us in the ballpark but I wouldn't rely on them to be accurate. Please make your reasonable offers and they won't be rejected. I may counter-offer, but at the end of the day, I need to move my collection.
I will gladly negotiate a per-card price for large batches or for the whole lot (just under 27,000 cards).
I'm not sure if this will work but here's the URL to my collection for sale: https://www.tcdb.com/Collection.cfm/member/ScubaCamper/collection/1
I'm in the Southeast US and will gladly meet up for local pickup; otherwise shipping will be on your dime.
