On November 25 in Geneva, Numismatica Genevensis sells a presentation specimen of this coin in a stunning condition, lot 581 estimated CHF 500K. Here is the link to the site of the auction house.
The engraving is very sharp and very attractive, with Basel symbols including a spectacular basilisk with outspread wings, the coat of arms of the city and the arms of the eight associated municipalities, plus a cornucopia. One side displays a wide panoramic view of Basel with the houses over the Rhine, a bridge and two boats.
The only other surviving copy, in poorer condition, is preserved in the museum of Zurich.
I invite you to play the video shared by Numismatica Genevensis showing the great quality of carving of the Basel cityscape :
