G'day Stackers, hoping for some advice on a coin purchase. Is $5700 a fair/ reasonable purchase price for a full set of PM 1997 Nugget coins in the Jarrah holder & vinyl protective case? The set is 1/20, 1/10, 1/4, 1/2 & 1oz. Not much of a yard stick, but kjc had a proof 97 nugget for $3100, presume sold in the last few days, as it's no longer listed. Thanks in advance.
