If you are selling via a dealer then their commission can take at least 20 percent of good priced items up to 50 percent of cheapies, ebay and PayPal will be about 15 percent so if you can find someone to sell them it is only really 5 percent difference
I was offered between 35 and 60 percent of value when I wanted to move a few on a couple of years ago.
Pete Smith and Des Parker are 2 dealers I have bought from and would recommend them
