I live for this! Fresh, new, old stock antique buttons that are still on the card. Never used, many of these still have their original vibrant tint and need little or no cleaning. I've been lucky enough to find a button seller that has many different types of antique buttons in sets.
Multiples are wonderful to have on hand when designing jewelry pieces because they can be used in pairs for earrings, or larger groupings to establish a pattern for a bracelet or necklace.
Marked on the backs of the cards is the price for these 100 years ago, most sold for .07-.20 cents a piece. With so many different cards & types of buttons, I'm starting to feel like a haberdasher.
