Denier with interesting cross (spade-like rounded clechee?) [επιλυμένο]

Currently trying to identify a denier which only has its cross motif intact. I'm intrigued by it because the cross itself is made of four spade-like arms that I can't seem to find anything like. The closest I can compare would be to a clechee cross or occitan cross, but mine is much more tapered and rounded.

My coin is silver or billon, clearly hammered, 13mm in diameter and quite thin. I am confident it is a denier, and have been scouring through French provincial and Crusader types to no avail.

 I've attached raw images, my attempt to identify the present pattern, and an extrapolation of what the whole might look like. Any guesses or leads are greatly appreciated!

 Trying to find [image search] what such a shape might be called .. 

 omitting for now the small circles. Nothing found sadly. 

It's very peculiar that nothing of the sort seems to come up… “cross with spades on the end” just doesn't seem to be a motif on coins or otherwise.

This is close; it is described as a “Black Greek cross with heart-shaped filials”. The title is “Escudo Hermandad (El Prendimiento)” which may somehow relate to a Spanish sacramental brotherhood? I can't figure out the connection, though, if there even is one.

Definitely a Vienna pfennig one sec
