Well it'd still be worth "1 dollar". But that's the problem with talking about the value of a dollar - the typical unit of measurement is the dollar itself.

However, in 1900 you used to be able to buy 70 pounds of potatoes for $1. Now you can buy 1 potato.

So yeah I would say that's pretty expired.

So. that isn't "money", that's "debt"; and, in fact, the article covers this...

> Money could be deposited in a bank, whereby it would retain its value because the bank would be responsible for the stamps. To avoid paying for the stamps, the bank would be incentivized to loan the money, passing on the holding expense to others. In Gesell’s vision, banks would loan so freely that their interest rates would eventually fall to zero, and they would collect only a small risk premium and an administration fee.

This only goes back to 1913, but says $1 in 1913 is worth $30.65 today. That's pretty rough. https://www.minneapolisfed.org/about-us/monetary-policy/infl...

If it's sitting in the bank, it isn't subject to inflation, only interest. Depends on the interest rate. With 2% compounded annually, it would be around $11 today. With 5%, around $400.

If you open a bank account today and deposit $1, you'll be in the red next month due to maintenance fees.
