Most likely it is Gold shell (gold plated) But it could be a jewelers mark.
it can refer to the jewelry makers initials or company initials. using those same intials GS usually means gold over silver when it is stamped inh the order of GS.
417 STANDS for 10 kt gold. Not sure about the gs
GOLD SHELL = Equals fake or gold plate If the GS stamp is inside of a diamond shape it's the makers mark for Gottlieb & Sons.
The GS Ball does NOT exist in the games.
You can't get a GS ball in Soul Silver. You can only get it in a Japanese Pokemon Crystal. Sorry.
a silver apricorn makes a GS ball in Pokemon HeartGold or SoulSilver.
i can tell you, but whats a gs ball? GS stands for Gold Silver
No - it does not mean gold over silver at all. It means "gold-shelled" which is another way of indicating that it merely gold plated. The base metal is rarely silver (or the plating would probably be called vermeil and not be hallmarked GS) and is probably just inexpensive base metal(s).
there is none
No.
the gs ball is not real it's only in the show
