So I’ve recently bought an expensive gba game, Pokemon Leafgreen, I decided to look the inside of the cartridge and I’ve noticed a discoloration

That should be colored gold right? Like this?

What is the reason why it changed to silver? Is this normal? What should I do? Can this ruin my cartridge in the near future? Help
