Augggh, another ingot!!
It sure looks that way Hogge, best way to be sure is to have it tested by an assayer, it is a simple acid test that is done right in front of you and it only takes a few seconds before you know what you have and what purity it is. There is a fee invloved, but it shouldn't be that much and it will be worth it to have the assayer's test report in hand, that way if you should ever want to sell it, you'll know the value, and you'll have documented proof for the buyer on what he/she is buying.
