Can anyone tell me if this is a relatively modern blazer button or is it possibly 19thc? I found this on an old homestead site that was occupied from approx. 1860 - 1930. Now, I've detected parks and have found modern versions of this button, but this one kinda 'feels' different to me.
It's heavily constructed, thickly cast and it's obviously a two-piece that originally had a metal back, but is it possibly 19thc as opposed to 20thc?
Thank you in advance for your thoughts,
Dave
