Mystery Item ?! Playing Card Wooden Matrix XVIIth Cty

MISTERY ITEM ???!

Stunning and rare playing card ? wooden carved (cormier) matrix, with inscription N° on a coin and space to complete the text/title with a number

Austria, early XVIIth century
XIXth or early XXth cty (for sure) Handwritten label sticked on the back about origin/provenance and age/dating " Convent of Betz willer wreck between Rohrbach and..., destroyed 2 to 3 centuries ago and are/of which... remains at the end of the last century"

Matrix seems me certainly XVIIth cty; I ve found any informations about the Convent mentionned or its place. And it's not easy for me to read all the text of the paper.

My website Proantic fans and only curious people who could have ideas, more informations, or only a mind are really welcome !

Perfect condition

Sizes 7,5cm lenght; 6cm high and 2,4cm thickness
