Kind regards
Do you mean on the outside, or underneath the hologram?
if on the outside, check this page, let it load.
Ctrl-F in your browser. Search on the code you are talking about, make sure you do it CaSe-SeNsItiVe when you put it in - Does it find anything?

Edit - to cash them out, you must peel the hologram to reveal the private key or QR code. (Sorry I am not sure 100% what is under a BTCC coin) , but if a readable string or QR code, just use mycelium wallet for android/iphone if you can, then do cold storage import in the app to sweep the coins/chips whatever)..
