I saw that one had sold for $750 at an internet firearms site and it's expected price was in the $1,100 - $1,200 range. It had nickel/chrome plating and no sight. Someone was advertising one in the Omaha World Herald for $550.
one in good condition about 600
Depends on condition. Price range from 500-1000
Gold plating depends on the spot price of gold. Gold plating is extremely thin, but gold is expensive too.
50-500 usd
This will depend on the material you are interested in plating with. As the price of gold goes up, even plating with gold will become more and more expensive. Plating with silver will be less pricey than plating with gold.
A lot depends on condition and exact version, but prices tend to start at around $3,000 for excellent condition.
No details. Price range could be 250-750
