I have the pink Sweetheart charm from the 1980s and the insert with the title of "My Lttle Pony Mummy Charms." There's a poem in the middle that starts, "A My Little Pony Mommy is..." The copy right on the bottom says 1986. The charm has some discoloration in spots. In looking on eBay, I see an insert and charm for $25. Offer?
