Nope.
There’s a 28% collectibles tax that you are ignoring.
There was a case a few years ago if a business trying to play gold coins both ways. Iirc they were paying contractors the face value of the good coins but then claiming a business expense on the melt value. I believe they ended up losing in court.
And then there is Greshams law. The main reason people don’t do this is that bad money drives out good. So if you are holding $20 in paper fiat and $20 in gold, your trust in the value of the gold is higher than your trust in the paper fiat. So you’ll preferentially spend the paper fiat first and hold onto the gold.
You are right @ nealmcspadden you can't have it both ways. So you claim that you used the "lost money" on advertizing and promotion, just like when you give senior discounts, etc. But you cannot claim that the money you used was worth more than the face value. If you buy an item for 1 dollar face value silver and then try to say you lost 19 dollars because you used silver would not make sense. If you sell an item for 1 dollar face value silver when you normally would sell it for 20 dollars face value paper, then you claim that discounted sale as a promotion. If you are purchasing for the business and reselling, then you might show a larger "profit", but would offset that with "promotion" costs granted to your customers.
Thank for the input.
