Just found these in my jewelry box. Been a while since I've been in there. If I remember correctly goty the 777 tie tack/lapel pin at a slot tournament at the Flamingo Hilton. It has the Hilton logo stamped on the back. The 4 suits of aces is 14K gold. Its stamped on the pin. I have no idea what I want. If someone is interested in these, drop me a line. If someone actually/specifically collects these, well I won't be surprised.
