how to use coins in microsoft solitaire collection

Apparently not. Seems kind of dumb to have them.

Hi, I hope you're doing great out there.

I'm an Independent advisor and I'm here to help you with your concern.

Coins help you track progress in Daily Challenges. The coins you earn by playing Daily Challenges will help you track your progress towards the bronze, silver, gold, or diamond badge that month. If you click 'Daily Challenges' in the app, you'll see the coin progress bar for the month at the bottom of the screen.

Let me know if you have any questions. I'll be happy to clarify it.

It was a pleasure interacting with you on this thread. Great hug!

Other than tracking daily progress, do the coins have any other value? For instance, can I buy additional games with them?

When you first logged into Microsoft Solitaire Collection, it created a GamerTag/Username to be associated with the Microsoft Account used when opening Microsoft Solitaire Collection. This is used to track your progress(score, badges, achievements, etc).
This GamerTag is generated randomly and may be changed(1 time for free) if you wish to do so.

Information on how to change your GamerTag can be found HERE.

A 1 week free trial of Premium Edition is given when you first sign into Microsoft Solitaire Collection. The Premium Edition grants access to bonus exp, coins, tournaments etc, as well as Ad-Free. At the end of the free trial, you are given the option to
purchase the Premium Edition subscription or continue to play free, without the Premium features.
