Not reproductions.
I checked that out.
These are legit as far as I'm able to find out.
They are parts left over from Billy Gladstone's supply.
They are indeed worth more than regular drum badges.
The snare drums are going for more than $20k these days. So... say one of the 50? original snares turns up and needs one of these 'original badges... it would probably be well worth the money.
