This is one of the last of this type I have, and the buttons you see listed are all that remain of my Spanish Florida buttons. What you see listed is it; no more.
Professionally conserved, by me, a former museum conservator.
I have terrible eyesight, so I can work with these materials only a few hours per day and under extreme magnification.
Mechanical cleaning methods are all I use (never chemicals).
Button dates from 1740 to 1785.
These buttons were used by Spanish Colonial troops, and in this size, adorned their uniform or possibly gaiters. This button was recovered from St. Augustine.
The button is hand cast, has a semi-convex profile (from polishing; as cast it was flat), is made of copper alloy, and has an integral shank with drilled eyelet.
Standard US quarter shown for scale (not included).
I purchased an extensive button collection from a former colleague back in 2015, and I have been studying and cataloging them since.
My colleague was a well-known amateur archaeologist. He used metal detectors and pioneered some of the search methodologies still used today. He visited quite literally thousands of historic sites here and the US and abroad.
