I am possibly about to make a large trade for AFA G1 Transformers and I want to make sure I don't get scammed in any way since I've never had an AFA toy. Basically is the only way to tell if anything is faked is to match the serial # with the AFA database?. I'm sure they are legit I am just nervous because I am giving up something very rare and hard to find and don't need to have to hunt somebody down if I get burned on this. Are there any other tips or things I should look out for? This guy should have receipts if he got them graded himself correct? Just want to cover my bases, any help will be appreciated!
