Approximately 30 years ago, at a fundraising auction I picked up a collection of Swamp Thing comics - almost all were in sealed packaging where they have stayed since my purchase. I have Issues 1-24 plus House of Secrets 92 -first appearance. I'm in the process of sending many of these to CGC for grading and packaging. I am only sending those which I believe will be graded 8.5 or higher.
That would be House of Secrets 92 and Swamp Thing - 1,2, 9, 12, 14, 15, and 17. I anticipate many in my collection will rate 9.0 and higher. I believe only two from the full collection would rate 7.0 or lower - issues 3 & 4.
Where would I earn the most - Ebay, Comic Link, or Comic Connect? Would selling as a full collection or as individual pieces generate the highest prices?
Thank you for any guidance any of you could provide.
