Paul is correct. I think you have posted all the varieties. As for the last two you posted, the extra marking means 'pure silver' so these usually get a higher price. Although they are indeed not the real thing, they are certainly not fakes. Replicas, yes, but not fakes. The group that made these in the 1970s (and perhaps later) never intended to deceive anyone. They were given to veterans.
The reason I wrote that is I have read on other forums that people are angry that so many fake ones are being sold. If a seller is claiming that it is authentic when it isn't, the medal itself (and its makers) are not at fault; the seller is.
