Underground Sea

Underground Sea is classified as high counterfeit risk: Revised Underground Sea is one of the most-counterfeited dual lands. Check the print quality and cardstock (real cards have a distinctive blue inner core visible from the edge), the rosette pattern on the back, the security stamp on planeswalker / mythic cards from recent sets, and confirm the collector number and set code match the official Scryfall record. For high-value copies we recommend submitting to a professional grader (PSA, BGS, CGC) for tamper-evident authentication.

As of the latest data, the current market reference price for Underground Sea is $941.24; there are no active listings on The Game Traders right now.
