after raiding my copper jar last night, ive found one of the undated (both sides) 20p mint mule.
the genuine undated coins seem to fetch about £250 on ebay if sold by someone with good feedback. ive got 170 on ebay 100% poss feedback.
so what do people reckon? should i sell it now or wait, like will it increase in value? there are about 200k in circ, so £250 seems a good price..
sell now or wait?
