Task Unit Trident 2019 SEAL Team 7 Navy Challenge Coin. Please see my other listings for more challenge coins. If you are looking for a specific coin for your collection, as a “memento” from a previous unit, to replace a coin that was lost, or for a gift, please message me! If you are purchasing an expensive item, I highly suggest you insure it at the full value. Please let me know if you are purchasing multiple coins and then let me know when you are done and I will send you a combined invoice.
