Hi All, As I have very limited knowledge of numismatics, I was hoping that some of you very informed people here can help me with what would be a reasonable price for a 'S1 Year of the Snake $25 Gold Proof Coin' would be as I have been offered one to purchase. I have googled & searched fleabay but can't seem to find too much information. The encapsulated coin, the presentation box & coa all looks to be in excellent condition. Any help would be much appreciated. Thanks in advance diggsy
