THe cruciform No4 is one of the earliest fakes, along with the Kukri sockets. THere were many copies sold inth e60's that werent made as fakes but for collecting, trouble is these now have 50 years of age and are harder to tell by th enew look.
Etched 84/98s were started in the UKin the late 60's by a guy in his garage for fun, now people sell them as grandads pick ups and people pay stupid money
Germanstuff has been copied for years as th eorigianl Dies for the medals and badges were "capture" and in some cases the german companies themselves made them for the "vet" market. Horster is supposedly to have made 84/98's for occupying GI's to send home. Now you could collect just fakes, I used to try to keep up and get everyone I could, that is no longer possible and some are complete fantasy.
