Of have found 2 of them myself and you can see from my post I have is older then the other one wich has newer text style like yours. Also there is info posted by others about the medal. Hope that helps.HH
There was a lot controversy in the 1850s about what Catherine de Labolets(?) vision really saw. She was dead by then, so the church just decided that the medal above was the correct version. The other version, made by Vachette, is worth big bucks. The collecting of "apostate" medals is one of my passions.
