Trophies are collectibles in Subway Surfers. They are quite rare, and can only be collected from mystery boxes. Other than showing how lucky players are, they serve no use in the game (until Rome 2014 edition). They can find them at the 'Me' menu along with the characters selection and the hoverboards selection screen. At the start of the Rome 2014 edition, trophies were able to be received again multiple times due to the new Spraycan Awards introduced at that edition. There are 8 trophies in the game:
Gemstone Description: It belongs in a museum!
Gold Bar Description: Directly from Fort Knox.
Classy Clock Description: Show your style like Flavor Flav!
Dollar Chain Description: Bring something bling to the party.
The Paperweight Description: A little Gold Sapiens.
Headphones Description: Groove is in the heart.
Platinum Record Description: Bring the beat back!
Cassette Tape Description: Retro musicology.
