How do they determine the exchange rate?
The same as if you were buying euro’s or other currencies, the daily market value listed. I found 1,500+ euro’s in a money belt I used in 2015 for a trip to Italy a few months back. Oops... I paid 1.02 USD for them they are now at 1.12 USD each. It changes constantly.
That’s what I wondered. Silver is down pretty much.
Wonder what happens if there is no interwebs to look it up.
