A beautiful 1.5-inch brass coin with the crest of the Nuclear Power School - Mare Island Navy Ship Yard (NPS-MINSY).
These coins are designed and only available from me. Would make an excellent addition to your collection or for your favorite sailor!
OPTIONAL: Our Air-Tite acrylic cases provide the ultimate long-term protection for your coin. They are made of crystal clear, hard Acrylic and will never yellow over time; the foam rings are made of Volara and both are free of PVC that could damage your coin.
