These are Australians

Age and patina could very well be the culprit. Here are some other examples of USCG and USN pins; left to right: Pancraft, H&H, N.S. Meyer and one unmarked with Sterling on the N. It's interesting how the USCG ages differently.

It has a chain line that replaced rope on these badges in very early World War II.  Because it has an open catch verses locking catch, I would say it is one of the early "chain" examples.   Made just prior to the "strategic metals" requirements of WW2, so it is not sterling.  I think the blackening is just a loss of the plated finish and oxidation due to being exposed to moisture, etc over the years.  You can see remnants of the original gilt plating on the reverse top.

I love the salty patina on USCG and USN badges and pins, and you can tell it was well used by someone, with wear patterns and a drip of white paint on the top and back. The moment I saw this, I had to have it. I’m assuming it’s a 30s or early 40s Hilborn-Hamburg. Has anyone seen any USN badges or pins in the blackened plating? Any thoughts and opinions welcome.

Bluezebra, First of all, your AFH M1905 dated 1943 with brown grips would be a prize in any collection.  However, an AFH M1 UNCUT dated 1943 is super rare.  The first one that I think anyone from this forum had ever seen was found on ebay in 2021.  It was bought by a forum member for over $1200.00 as I recall.  No photo that I have found has been published in any book.  Most collectors had concluded that it did not exist until that one finally showed up.  Had the ebay seller marketed it for what it really was, and had good pictures, it may have gone much higher.  No other example has been seen since (to my knowledge).

The flag under the USCC flag is a Navy #7. They measure 5.14' by 9.77' so its big. This particular one has heavy wear from service (not moths or rodents). You can see the issue that flag collectors deal with, you can't really display it except on the wall for a short time. I'll leave it up for a week or so to air it out and then it will likely get folded up and either put in a tub or in a glass case with others. No history on it, seller bought it "in a box in a barn".    Sounds like your CC group is fairly large. Is it from your family? Again, I hope you're able to keep it together. 

Pretty sure thats a blank for sim guns or conversions.

Great collection.

It looks like a "798" to me... Though I have no idea, why it would be hand-drawn or what it actually stands for as I only know the armor patches with the band underneath them... I have seen them without the band, but never with a written number...
