I have a bunch of those myself. One of my two sons was born in 2000 so I was trying to put all 100 of the Matchbox 2000 cars together to save for him, I found maybe 3/4 of them. I'll have to see which ones I am still missing.
i had 50 or sixty of those. i found someone who bought the entire lot for $100.00 several years ago. i feel lucky.
also had the gold cars for the challenge. won that 57 gold chevy. one of 750. sold that entire collection including the 57 chevy for 350.00. that was 35 gold cars. not bad for 36 cars which i couldn't get half that for now.
now i am stuck with all these frightning lightnings, and speed racers. no one will you squat for.
i'm getting out of all collecting, except greenlights or hot wheels,.........hence the selling of everything.
