@atilla, first welcome to CCF. Second, while it is helpful to have overall photos, please add a couple close-ups of the specific areas which are of interest. When I enlarge, crop, and enhance yours, they are too pixelated to be helpful. Thx.

You have several things going on with your coin, but none are a premium for the coin. 1. There is an issue with die wear on your coin. The reverse is showing Progressive_Indirect_Die_Transfer This happens as the dies age. It is basically a upside down inverted ghost image on the reverse.
2. On the Motto on 'IN' it appears that there is a slight grease fill. How you can tell it is this, is that the when the die gets grease into the deeper part of the die, because the top of the devices are tapered, when this is filled with grease the coin will show wider devices. The more grease the wider they get. Eventually the devices can go away when they are filled.
3.There looks like some Machine Doubling is also altering the jaw and the mintmark area. (RPMs (Re-Punched-Mintmarks) are n o longer found after 1990 as the mintmarks are part of the design. If the mintmark is doubled, it could be a doubled die, but not in your case, it is just slight Machine Doubling. While the coin is nice, it could be a hole filler in an album. But for a premium for this coin not more than face value.
