I can’t speak for this particular coin, but I did something very similar just recently when listing an Elizabeth Lis penny on eBay.
I couldn’t decide which way to bat with it (buy it now with best offer, or auction) and ended up going with auction, thinking it would find its price!
It sat at .99p for a week, with people watching and then leaving…I guess thinking that it wasn’t genuine, I don’t know?
Anyway, point is, it sold for £82 and, when it did, I had three emails offering me more, with one person saying £200, which is more or less what I thought I’d get for it.
Really difficult to know what to do when using psychology to sell on eBay…sometimes it works to good effect, on other occasions it bombs!
I’m not calling this coin at all, but sometimes the genuine articles do turn up with a .99p start!
Maybe not this one, though????
