When it comes time to fill out a tax return IRS rules say any items taken through trade and barter are to be assigned a fair market value and that amount should be reported. And of course they use the dollar sign $ throughout the form and the word "dollar" throughout the form, charts and regulations. And since they wrote the form we can assume they really did mean dollar when they said it.
But what exactly is the legal definition of a "dollar"? If you visit https://online.kitco.com/products/3004/1_oz_Silver_American_Eagle.html
you will see the $1 Silver Dollar. It says "dollar" right on it and is is minted by the US Mint which is authorized by the Congress and the US Constitution to produce our nation's coins and money. but if you look at the coin here https://online.kitco.com/bullion/completelist_USD.html
you will see it has a list price of USD $ 30.94 ea. Wait a minute! They want 30.94 Dollars to buy ONE DOLLAR? Why would anyone give almost 31 dollars to get only one? That is crazy!
Well, we all know what they mean. They want 30.94 FEDERAL RESERVE NOTES in exchange for One US Dollar. My point is that the legal tender laws did not make a Federal Reserve Note a dollar. The dollar was, and still is, a silver coin issued by the US Mint that contains the legal standard weight and purity of silver. Bear in mind the company that owns the website is merely a private company so what they call something has no authority when it comes to legal definitions.
But when it comes to the IRS and tax documents we know they have to use legal terms and definitions. And since we need to determine the value of barter items in dollar value shouldn't we honestly say the value in dollars is the exchange rate in FRNs divided by 31?
