What is value of a 1922 gold peace dollar with the eagle upside down when you flip the coin side to side?

It's gold plated, not gold. A gold coin that size would have been worth far more than $1 even back in 1922. The good news is that the underlying silver is still worth at least $10 or so based on whatever the current spot price is.

The upside-down eagle is normal. Did you look at the coins in your pocket change? ALL U.S. coins have their reverse side oriented 180º to the front.
