Yes, there are a bunch of fake ones or ones recently made on Ebay. Ebay is full of recently made SA's (copycats) made for the collectors market. Some are mixed in with legit 90's bootlegs in three-packs which makes it confusing to newer collectors.Crazy prices! good for you mate.
A lot of those early ones come out of rubbish tips im sure you know Steve, still turning up to this day.
