If you've got old T tokens lying around, they're currently worth $1.25 if you use them in a CharlieCard machine.
Although the MBTA got rid of token-operated turnstiles over five years ago, the tokens are still worth the money, and you can use them to add value to your CharlieCard.
After Saturday, that will change.
Joe Pesaturo, a spokesman for the MBTA, confirmed that starting July 1 old tokens won't have monetary value, at least as far as the T is concerned—they may be worth something as collectibles.
So, if you've got drawers and jars filled with old tokens, you may want to cash them in this week.
Of course, you may want lots of old tokens, and if you've got any other ideas about what to do with them, let us know in the comments section.
