THE CACHE IS NOT AT THE COORDINATES LISTED ABOVE.
18 Feb 2022 Made a change to the puzzle to make the first step more obvious.
At present, access cache from the given Parking Coordinates.
Coins were first used from about 1200BCE
The earliest known civilisations to use them included Ancient Greece, Ancient Rome, Ancient China as well as several ancient Kingdoms and Empires.

An ancient Roman coin.
The coordinates for GZ can be worked out from the letters below.
There are three short steps. This puzzle does not have a high degree of difficulty. Most people should solve it within a few minutes. Some may take only a few seconds.
Use the Geocaching Toolbox or a multisolver for the first step. The name on the coin is a hint.
The Puzzle:

The cache should be an easy find. Not far from a sealed path.
