Here the original price, 650F (French or Belgian Franc) --> FR = 140,08 Euros, B = 16,11 Euros.

I think it's Belgian Franc (before the euro), given the price at the time. For example, the stone "Special Stone Only for God Razor 12x3cm) cost 4.60 French Francs, i.e. less than 1 euro.

I am sure at 99% that this stone is "La Veinette", according to this study, we can read "Recognizable by a thin yellow line visible in the BBW layer and this in a few mm from the Coticule."

We can see in the photo bellow the thin line at ~1mm from the coticule :

I haven't tested it yet, I don't want to damage the price tag
