Haha.
Nah, Krugerrands are the most common gold coins out there.
Getting circulated ones (as in not a specific year and not necessarily factory fresh) means it is both cheaper but also more fungible with a smaller spread between sale and purchase price.

It is also made to be circulated (the added copper (IIRC) adds strength to the coin. The gold content is still 1oz, so the coin is slightly heavier)

So for instance, a circulated Krugerrand (as in not in its original plastic casing), can be easily validated by a ping and density test.
No fancy equipment needed.

Contrast that with bullions for instance that can only be verified at a dealer.
