Hello all. Have a question for you concerning a Hot Ones Hot Wheels I bought a while back. I noticed that it has a serial number, I think, on the back of it. It is E03. It's the '84 Hurst Olds car. I also have the 80s Firebirdone, but it has a much bigger number printed on the back with numbers and letters. My question is this: Is the E03 printed on the Hurst Olds card indeed a serial number? And if it is, does that indicate a low production number? Wondering if I have a rarity or something here, or if it has value to collectors. Not really interested in selling it, but I am curious. Thanks for any info.
