MSU Monogram Engraved Initial Letter Font Vintage Cuff Links university

I HAVE HUNDREDS OF TIE TACKS, TIE BARS AND CUFF LINKS. cuff links: 0.76" x 0.59" (3/4" x 5/8" or 19mm x 15mm). I always try to point out any clear blemishes and condition. 0.25" = 1/4" or 6mm - pretty small for standard button holes.
