thanks!

The problem that I find with high premium bars that come sealed such as perth mint and pamp suisse is that they can be easily faked. No one wants to lose the premium by opening up the packaging, which means no one is able to do a scratch test which gives away fakes easily. That's why I don't hold any high premium gold/silver.

So im not sure why, and i've mentioned this before why people think the scratch test means anything? or that you need to remove a piece of precious metal from an air tite or a case to verify its resistance and other methods?

Actually the acid test is probably the worst way to test as you are only scratching the surface...so what of you have a nice gold bar that is PLATED? and the inside is filled with tungsten? your "scratch test' would telll you it is real, but its a fake.

thanks!

There aren't many ways to test gold for purity, but by not being allowed to inspect it outside of it's packaging that high premium bars have, the ways in which you can test are greatly reduced.

The weight test is a good test which you cannot do if you have to weigh the packaging along with it.

I would imagine you can find the total weight for both the bar and package in the sealed bars and coins. For instance, an NGC slab that holds an american eagle is 40 grams. In terms of the multiple tests, I am pretty much clueless. I would imagine there is some type of electronic scanner that can measure density and purity.

There are many tests you can perform without touching the actual metal

Through a slab, etc. If you aren't aware, GIYF

But hopefully I will be able to meet up with the OP to see, although OP, you haven't replied to my last few messages??? so who knows.

Thanks!
