Mainly i feel because ebay is such a huge coin market people are looking for something for nothing and think everything is cheap.The coins you mentioned the average person (inc.me ) would not have a clue about and will just buy it for £+++ think they have got a bargain ,put it away and look for another coin thats cheap.
Sad and pisses me off , if you look at anything on ebay not just coins its full of sellers trying to have people over
Well spotted though and thanks for posting them.
Although not my thing you have some lovely coins for sale on eBay......Your obviously one of the decent sellers so HAT OFF to you
