Button with a crown on it

A buddy asked me to id this button for him in my Tices US Button book.
I doubt it will be in there, because it looks british.
Was wondering if anyone has ever seen this design, and knows anything about it.
Thanks

It kind of looks like one I saw on tnet recently, pictured below, but the one above has a slightly different design and looks much older.
1970s blazer button pictured below.

Well I finally got my buddy to send me a pic of the buttons back.
the back isn't in the best shape, but here it is.
Just thought I would kick this up to the top one more time to see if I get any responses.
