Why do so many 2/3 Brunswick Talers seem to survive in great condition with color?

Why do so many 2/3 Brunswick Talers survive in high grades with particularly attractive color? I've bought several over the years, while in the same time period I've hadly found a similar quality Taler. Specifically, the 1677 Brunswick Luneberg types survive wonderfully. I bought three last month.
Here's one as an example of the quality and color.

Maybe AT (assume this means artifically toned) but I have had similar ones 10 years ago ....the same date yet never a taler from the same period.

1836 Capped Liberty
dime. My oldest US
detecting find so far.
I dig almost every
signal I get for the most
part. Go figure...
And where are the pic's of the other two?

OK Maye not common in gem but more common than the taler. Also, perhaps the silver composition allowed them to tone much nicer than other silver coins of the same period. Here is a picture of one of the other 2/3 Talers you mention as being in Long beach last week.. Also great color and definitely not AT in my opinion.
On the earlier topic, I dont think the 2/3 is AT. On a 20 year old coin.....yes, but not on a 320 year old coin in gem.
By the way, are you trying to corner the market on 1677 talers?
Edited to add - I seriously doubt they're AT.
I'm going along with NT, but who can tell

Sulfides are generally more natural in shades of brown with minor exceptions, vibrant and electrical coloration is not the norm.
Well, just Love coins, period.

Here is the third one from Beverly Hill (Goldberg) not Long Beach. I doubt any of them are AT
Great pics and now the big question is, why is Johan facing left twice and right once? Believe it or not I have no idea

Wowee, nice coin.
