I HAVE HUNDREDS OF TIE TACKS, TIE BARS AND CUFF LINKS. cuff links: none. tie tack/bar: 0.67 " x 0.66" (approx. 11/16" x 11/16" or 17mm x 16.5m m). collar bar: none. I always try to point out any clear blemishes and condition.
The AMA American Motorcycle Association Vintage Tie Tack Lapel Pin D58 is a great fit for collectors of American motorcycle-related memorabilia.
