1. Check the serial number of your Credit Suisse gold bar on the front side. You should find other essential information stamped on it, including its gold content and fineness.
2. Above these details, see if there’s a rectangular outline with the words “Credit Suisse” carved on the bar. Below the words, you’ll see the French phrase “Essayeur Fondeur,” which means “melting tester.”
3. Check for diagonal logo boxes featuring the words “Credit Suisse” on the back of the bar. Both the front and back should display capital letters with the same font.
4. Some fake Credit Suisse bars display incorrect markings and details, whereas others don’t have serial numbers.

Regardless of weight denomination, all Credit Suisse gold bars contain 24-karat gold featuring .9999 fineness.
