Apologies, but I don't speak Dutch. Just to verify, I believe that this is the coin that you are referring to:
"2016 Niue Island Artificial Intelligence series Code of the Future $2 Silver coin Glow in Dark Antique finish 2 oz"
Metal: Silver
Country: Niue Island
In fact, here's a certified example from NGC: https://www.ngccoin.com/certlookup/4594752-017/70
I don't know the market value of this coin where you live. I have seen it listed on eBay, though. If you do a search on the exact name, you will probably see listings in your region.
