This is a collectable unique steel button making negative originally for use in the manufacture of press molded glass buttons or cabochon beads. The negative is intricately hand engraved in toughened steel and was used to create the actual button mold in a softer metal material which would then be set in long metal pliers and used to hand press fancy glass buttons.

To reproduce a new button negative today would cost at least $2000 for the paper design, engraving work, finishing and patenting.
