Wow! You found a Byzantine button on a farm in Maryland!!!! Space aliens were involved here for sure😁.    Seriously, it is very interesting that the designs are so similar.    mikie    

Capt. Case- They pull all the knuckle knives off of internet, or ebay. Try the edged weapons sales at the on this web site to get an idea. There may be one or two. Good luck! SKIP

You guys could be right, but this type of leather was originally soft...and likely did not originally have a finish on it.  100 years ago, elk or deer hide was often used.  If along the way, someone oiled or added some sort of finish or dressing, you could easily end up with wear and rot like we are seeing.     I think if we were examining this in hand, the age would be easier to judge.  That said, I am not sure why someone would go to the trouble of aging something like this to this degree.  

What is this worth 

Agreed it's probably Mexican but look how close it is to this Byzantine Egyptian coin. Interesting.   

Here it Comes - "the Big D*ck"   I shot this photo hanging over the signal bridge of the spud coming over during a Unrep from an AO in the Caribbean Sea, 1980   Refueling Probe, USS LUCE (DDG-38) 1980  

I think there is a lot more dating back quite aways.

Can´t get enough of regarding the last pictures, I wish I had something like this in my office...   Great to see your helicopters flying, they look fantastic! Nevertheless I´m still deeply impressed by your figure painting skills; mind-blowing!  Thanks for sharing & keep up your great work.   Lars

I found it on a very old farm along with many old 1700's,1800's stuff.

HMMM? I never even gave that a thought way up here in Northern Maryland but it's worthy of a look. Thanks
