In October of 2016, Munzee introduced Munzee Coinz, which are Extagz with numbers that can be discovered at both Munzee and Extagz . Currently, you can use your coins to track your capping activity and you share your coin codes with other players for them to discover.
In January 2017, Munzee introduced Coinz of the Month Club.
Your online Coin page will look something like this.
You can also choose to look at your "discovered coins" online to see where your fellow players have been capping. The owner of the coin does have the option to turn of tracking.
To discover a coin in the app, you will need to go to the tools menu and select Discover Coin. Enter the Munzee Code number and then click the check mark. (there is a separate Extagz number for tracking at that site).
The owner of the coin will get a notification that someone has requested to discover it.
You can also find your requests in your tool under "Coin Discovery Requests"
