The rare Binion's $10,000 bill is priced at nearly $100,000 or 10 times face value.
Indeed, a rare bill to find anywhere and issued 77 years ago.

But in comparison, gold value in 1934 was just $35 per ounce, so a $10,000 bill could buy 285.7 ounces worth of gold (assuming it was legal to hold that much gold as a private citizen, which it wasn't after the gold standard ended).

Today, at $1800 per ounce, 285.7 ounces of gold would be worth $514,260, or 5 times the value of the asking price of the $10,000 note on ebay.

This isn't a direct comment on the economy, or the pros & cons of returning to the gold standard -- which is a complex subject -- but still an interesting comparison to consider!
