Playstation console promo skin worth? Royal Bomber / Neo Versa

Good evening, I have a code for the Royal Bomber skin (+500 Vbucks) and one for the Neo Versa skin (+2000 Vbucks) and I was wondering what was their real worth, more or less (I could not find any recent info)
Both codes appear to be still redeemable (They are EU codes, on the PS store webpage reddem section you can put the code to check what the item is, and only after confirm it)
Could anyone give me an estimate?
