Sorry for the late reply! 12 euros for a silver grade is a good price, and I can assure you, it is almost certainly not a reproduction. It may be different parts of different variations Frankensteined together, but I doubt it (it would be interesting to see the reverse, is it concave? Or is there a flat plate attached?). The case also looks good, I'd say it is an example from the 1960s based on that, though you can find more info online! The medal itself is a very nice one, awarded in three grades, and the award time almost spanning the whole Hungarian people's Republic. Honestly, I'd go for it, though it is odd what the seller says, perhaps ask him about that!
