When you said “the image” I thought you were looking at the right one, and I thought it odd you were off several orders of magnitude from what I assumed to be your misunderstanding. That explains that. I had to go back and find your figure.
I gotta say that using "$" for both USD and COP is confusing. So you must say "USD $x" and "COP $x". Then why bother with the "$"?
futhermore the US Dollar itself stems from the Spanish Dollar:
"The U.S. dollar was directly based on the Spanish Milled Dollar when, in the Coinage Act of 1792, the first Mint Act, its value was fixed [..] as being "of the value of a Spanish milled dollar as the same is now current
But it's still potentially confusing, when stuff gets translated with no context for currency values. Especially, I imagine, if you don't know either Spanish or English.
The Dutch, ever innovative in trade, can lay claim as a bigger influence on the word “dollar” and the currency form itself, however, and colonial Americans traded regularly in Dutch daalders (we still pronounce it that way, unlike doh-LAHR/doh-LAHR-ehss for the Spanish varieties). Daalders themselves were descendants of Bohemian thalers, as were Spanish dollars. We just borrowed the neighboring dollars when the time came, probably due to our foreign policy environment at the time, trade with Florida, and so on.
I mean we have kilograms, meters and seconds. And they're the same for every country.
But "$" (dollars and other currency units) means different things, depending on the context. Similarly for ounces, pounds, feet, gallons, etc. So you're left with constructions like "US $" or "USD" or "USD $" vs "Can $" or "CAD" or "CAD $". Just as with "avoirdupois ounce" vs "troy ounce", "US gallon" vs "imperial gallon", and so on.
So anyway, I always write "foo USD", "foo EUR", "foo mBTC" and so on. To avoid ambiguity.
There’s a bit of americentrism down the confusing line of thought, for what it’s worth.
