Here's the link to this auction... it's so sad if she is a member selling it... why would you do that?
Sounds like it's an old badge though - didn't they stop inscribing the backs years and years ago? With the '25' engraved on it, maybe it's from 1925?
Hmm, actually, I just looked up the name on the badge at Sister Search, and she initiated in 1947. Doesn't say she entered Chapter Grand though... I wonder if we could contact her and let her know her badge is on EBay?
