We're here to answer any questions you may have about what happens to your extra Coin Tokens after the Monopoly GO Fountain Partners event. You will get something in exchange for the tokens, even if you won't be able to retain them for a later event. Not much, but some anyway. Developers wouldn't treat people unfairly. Let's discuss it.

After the Monopoly GO Fountain Partners Event Ends, What Happens to Extra Coin Tokens

As far as we know, all of the additional Coin Tokens you get during Monopoly GO Fountain Partners will exchange for Cash after the event is over. I'm not sure the precise exchange rate is; if you know, please share your findings in the comments. The main idea is that, depending on how many Tokens you have remaining, you may win a tidy several hundred thousand dollars (in Monopoly money, of course). After that, you may use them to upgrade your Landmarks, which will allow you to get more Stickers, Dice Rolls, and other goodies. Although it won't be entirely wasted, it's still preferable to spend those tokens for event prizes as long as you can. Don't begin hoarding tokens in order to pay cash.

So, yes, once the Monopoly GO Fountain Partners event concludes, that is what happens to all of your additional Coin Tokens. Recall that although every event clears the slate, the game never takes away the items you've won without at least partially compensating you for your pains. Although it never quite compares to what you would have received had you used the tokens during the event, it's still preferable than having nothing at all. The same applies to other items, such as the way that Shovels and Pickaxes convert into Dice Rolls. And that's pretty much all there is to know about the topic.
