Hi Liorst, gold plated items can sell for more then twice the actual gold value of these cards. if you want to know how much they are worth, here is an indication of different prices for RAM scrap in euro's.

I supect these are internationally comparable.
Personlally not interested i get my scrap for free mostly from friends,
Ebay is your friend. Shiny stuff sells.
The sky is the limit, your conscience may be the biggest limiting factor :wink:
Good luck. Martijn.
