I can sell around 95% melt at my coin club. There's a guy there that loves the stuff. Ebay looks good too though.
Assuming $60 with standard fee's and shipping costs of $3 those sellers are getting back of melt as shown below. Have you guys ever tried selling via the buy/sell forum here? Pretty sure you could easily get melt even for 40% as I know I have multiple times in the past.
don't pay more than melt for the 40% halves (same goes for the 35% war nickels) - their retail price mirror the daily spot price - the 1970D is scarce, so you probably won't find any of those at melt
