The exact date is difficult to read:
It's (16)23 of (16)25. The picture on Numista is from a 1625 coin but it looks as if the 2 is different from your coin, so yours might be a (16)23.
There are a lot of varieties in the legend. Unfortunately there is no information for the 1623 so determination of the date on the basis of the legend isn't possible.
If your coin is a 1625, of the four possible varieties it probably is the second one GVSTA : AD - OL · D · G · REX · S / SOLIDVS · CIVI · RIGENSIS · 25.
I think the A of GVSTA in in the left red circle and although it's not clearly visible there's definitely room for the A (which rules out varieties 3 and 4). It's also very clear there is no O between AD and the ornament at the bottom, which rules out variety 1.
So, I believe it's (16)23 or (16)25 variety 2.
