I’m brand new to this forum. I’ve owned my Beatles set of 4 autographs for 22 years. I bought them in Chicago. They came with a LOA from Frank Caiazzo whom I met and spoke with at the time. I thought I’d put them on eBay and did so but didn’t research hardly at all first. Caiazzo appraised them for $1,500 in mid 1996. The prices of a full set of autographs appear to be sky high. My questions-1) How do you know what is a fair price? 2) I’ve seen some autographs advertised with as many as 3 COA’s. Is it suggested to have more than one? 3) Are Beatles Autographs best sold at auction or is Ebay a viable option? Any other info would be greatly appreciated. Thanks in advance.
