For instance, how many US dollars or Pounds Sterling would one Galleon be worth?
Considering they are actual gold they should be fairly expensive, but is there some standardized exchange rate?

We know that there is an exchange rate; at the start of Chamber of Secrets, Hermione's parents are exchanging muggle money for wizarding money at Gringotts in Diagon Alley.
'But you’re Muggles!' said Mr. Weasley delightedly. 'We must have a drink! What’s that you’ve got there? Oh, you’re changing Muggle money. Molly, look!' He pointed excitedly at the ten-pound notes in Mr. Granger’s hand.
Harry Potter and the Chamber of Secrets
JK Rowling has said that the exchange rate at the time was around £5 to the Galleon.
Rebecca Boswell - What is the approximate value of a galleon?
JK Rowling - About five pounds, though the exchange rate varies!

Now, gold bullion prices in March 2001 were around £5.84 to the gram (https://www.bullionbypost.co.uk/gold-price/30-year-gold-price-history-pound-gram) - that means if a Galleon is solid gold, it should weigh less than a gram and be less than a twentieth of a cubic centimetre in size to remain consistent. Presumably they are instead some kind of gold coloured alloy, or Mr and Mrs Granger could easily become the richest dentists in Britain!
