Fort Sumter Referenced Badge

[CAP]

Dug this, what appears to be aluminum badge, behind an 1830's home, here in South Carolina.
So far, I have been able to make out the following:
One side has what appears to be crossed swords at top, then below sunrays. Below the rays it reads
"Fort Sumpter", then at bottom "1865".
The other side reads at top, "SUPREME....EGE" as best as I can make out.
Underneath that, "Charleston SC May 10 1892"
The top may have a hole but is blocked with rust or cemented soil matrix. I have had slow progress in cleaning
it. I have used hydrogen peroxide baths with little effect. I did have some success with elmers glue but discontinued that process because it seemed it may also have been taking some of the deteriorated aluminum with it.
Any help with identifying this artifact would be greatly appreciated!

I wonder if it's a homemade medal; Sumter is misspelled.
1861 was THE battle, retaken by the Federals in 1865.

I'm not real sure just what this exactly is, but here's a possiblity. It might be a badge from either a GAR or CSA reunion held at or near Ft. Sumter. You would have to see if one was held there on the date on the badge, but that would only require a short trip to the library. Other than that, I really don't have any idea as to what it could be. Still a nice find.

I think I found it -

http://cgi.ebay.fr/Orig-1892-Pin-Knights-Of-Honor-Charlstown-SC-Ft-Sumter-/120635406239

Very rare original from 1892 "Supreme Lodge K Of H (Knights Of Honor) Charlston, S.C. May 10, 1892" badge or pin for gathering at a special event with an image of Fort Sumter on the back and "Fort Sumter 1865". This unique badge is made of aluminum which was quite rare during that period in time and in fact was near the value of silver because of its rarity and newness. This pin measures 1 1/2" across x 2 1/4" high not including the bar pin.

Great Work Bramblefind! That's a direct hit!
Thank you for identifying this badge for me and thank all of you for your interest
and comments! I will go back to that spot and try to find the pin. Another odd thing
about some of the metal from period objects found in this yard: I dug several musketballs
that pinged out real high on the metal detector like copper or brass. They were lighter
than your regular musketball of that size. They were definately intended to be musketballs, they still had the sprue attached from being cast. When scraped with a knife the metal appeared white.
