I've never tried them myself but have heard them mentioned on this forum several times in the past as a reputable plece.
I get a flyer from a place called Miller's Mint and just looked up that coin. They show 6 different ones.
G4 = $339, G/F = $349, VG8 = $359, VG/F = $369, Last two are in the MS grades. They are in New York.
www.millersmint.com Ask for a catalog.
Still if you can find a coin show in your area, usually the best place for such sales.
