Better question .
Why make NCS rich ?
Most of the stuff they do to your
Coin when conserving it is easily
done yourself , IF you know what you are doing .
One example always soak any thing not obviously
NEW ( ie Gem Mint State , Gem Proof , or pleasing toning )
in either pure acetone or KOIN SOLV if you can find it .
NO rubbing or wire brushes!
The methods the conservers use are hardly proprietary!
Anyone can learn how to properly conserve coins for pennies!
