More Puffy Hearts than a Victorian Festival

I admit I don’t know enough about vintage puffy hearts – they have such a wide range from Victorian to the 1940’s (which Victorian collectors consider copies, but have more fans than any others, and more styles as well) to the 1980’s to present repros, which to my eye are no where near as crisp, and of course then there’s the patina….. and don’t even get started on the Walter Lample heart charms or you’ll go both broke and insane.
but no matter your level of expertise you have to see this puffy heart charm necklace auction – click here
– I’m just drooling over the frog one – and look at the engraving. I’d love it if someone who knows charms could please let me know about them?
