We were using beckett's until I can no longer find the magazine...Our collection is mainly 1/24 scales of mostly nascar (Action,Action Elite Rcca) those types We've been collecting for about 20 years...we have alot of 1 ofs..paints schemes, race wins, autographed ones...I'm not sure where to look..any help would be great! thanks

There are price guides out there, but what specific types of diecasts are you wanting to find values for? I know there is the Beckett Racing Collectibles Guide, which has values for NASCAR diecasts, but I'm not sure what else it lists.

I will message you a few sites I have run across that have appraisal values for diecasts. Keep in mind that some of the price guides you will run across are contributed to by diecast dealers who benefit from making diecast collecting appear like an investment opportunity by inflating values.
