Well at least I don't think this credibility is an issue with China medal collectors. It is important for coins, but not so much on medals. That is the reason there are lots of private medal companies producing lots of medals in recent years. Some of them are absolutely beautiful and very popular among the collectors. NGC will not grade these medals. So...
silverfever said:Is it worth getting copper/brass/bronze medals NCS conserved?
Thoughts anyone?
Personally I say NO. I don't know what conservation can do to these metals. The only problem I know with these metals is verdigris, but I don't believe conservation will solve this problem once you see verdigris.
I used to own an old China 20 cash copper coin. It is graded NGC MS62BN and has a verdigris spot. I believe it might have gone through NCS as there is some evidence some one has try to remove the verdigris. The result is not impressive though.
We know there are still tons of medals available in China and price is still so cheap, instead of paying NCS, I rather use the money to buy more, keep the spare as insurance in case some of them goes wrong. I still believe it is easier to take care of these medals than the precious silver/gold coins.
