Like countless posters before you , you would like to know the value of your diecast. You did not mention the condition, do you the original boxes? Anyway, Ebay is a reflection of what the market will pay, and never expect to fetch the ludicrous asking prices some idiots ask for, the items do not sell, the SOLD prices are what people are willing to pay. As for signed, for me, someone just ruined the model , I'll give you $20.00 to ship it to me, I might need it for parts later on.
