Melt is $460. $500 may have been an impressive going rate when gold was under $400/oz. in 2000, but not so much right now.
The S version of the Jackie are silver. The gold $5 was a W. Both have come down in price but the silvers have sat around $500 for 70s (looks more like 300-400 now) and the gold uncirculated were 2-3K at one point though more like 1500-2000 now for a 70 with the proof gold being like 500 to 600 in 70.
