The market on them is always unstable.. There are times they are very high,,and times collectors won't touch them unless they are very cheap.. That is a nice ring,,and not a cheap one!
Do yourself a big favor. - Don't be in a rush... Check , search around and see what they are going for.. Then you have choices of selling only there in the UK,,or the US and other places.
There is the auction route also but don't forget you pay a commission maybe 20% + or -.... Take your time with this one! and thanks for showing it here...,G.
