Hi, I have two 1:18 track white XY GTHOs in same condition. One is unsigned and one is signed on the roof by Allan Moffat. Thoughts on which one would be worth more?
Also have two 1:64 Peter Brock 28c XU1 GTRs, one signed by Peter Brock on display card at back of box, one unsigned. Which of these would be worth more?
Neither have COA for signatures.
