1643 Diner Louis Xiv, Curious Manufacturing Marks

This is a diner minted in 1643 during the "Guerra dels segadors" when France and Spain were fighting for control of Catalan territory. The bust is that of Louis XIV, the sun king.
The coin is very well struck, but off-center so it only has part of its legends, preserving on the reverse the complete date 1643 and BAR together with an I of the legend BAR-CIN-CIVI, in addition to two complete quarters of the cross with rings and points. On the obverse it preserves D.G. And L, in addition to more than half a bust of the monarch. The best thing of all for me, in addition to the conservation, the engraving, the color, everything is very good, is that in the uncoined part there are some triangular marks that it seems could have been left by a roller from one of the machines that were used during the process, this is still not very clear to me.





From what I have read in a Spanish forum, these triangular marks can be for 3 reasons:
-part of a roller without motifs
-collection points for excess material
-traction aid
-to recognize the cuttings from the shear and that no one would take them to sell them.
