Creditsuisse10g 999.9 Gold ID Process Clarification Request

Hello,

I ran into an opportunity to purchase the attached bar of gold.

Usually, I avoid these types of shapes when buying gold because of the possibility of finding tungsten within.

I wish I had access to one of those hand held fluoroscopic x-ray detectors for precious metal detecting which would make the verification process simple and straight forward.

1) Anyhow, please explain what karat of gold this bar should have.

2) What would be the least costly and accurate means of determining both the weight of gold and corresponding karat designation etc.?

3) Would contacting Credit Suisse and giving them the serial number assist me to determine what exactly I have here?

4) Is this type of information for this gold's descriptive narrative readily available on-line?

5)) Also, I only now own acid for testing 10k gold, 14k gold, 18k gold and platinum.

Could the acid used for testing platinum also be used for for testing 24k gold should the answer to 1) above be that this bar should be 24k gold?

6) Would it be necessary to drill into this bar, collect the resulting shavings and then melt them into a button for subsequent acid testing of some type?

Thanks for the advise.
