I've had a collection of Lego bricks made from a marvelled silver plastic since the mid 2000's. I got them form Lego land Winsor when they where selling off a lot of there old defunct sets when I found them in a bucket of generic Lego in the tent they set up to sell everything.
I have never found a single set that contains them and I have struggled to find images of them, I have in my position 2 2x2, 20 2x4, 12 2x10. The only place I know that they where used is in the model making studio to build a large model of a Boing 747 or so in Lego land Winsor which I believe they may have been exclusivity made for.
while I have been struggling to find info on them as is, trying to find a place to sell them has been a massive hassle as I am unsure where I can go to do it properly because if my assumption is correct, that they are rare enough to be worth some thing I need to take them to a place with buyers that have the money. I know that one of the solid gold Boba fets sold for 15000 but I don’t know where and I feel that Ebay/Brick link will not give that kind of money.
Any advice on what I should do and if my Lego is truly rare will be greatly appreciated.
