Found old Navy Brass Ship plaques

Super heavy plaques (about 4 lbs each) does anyone know what the purpose of these was?

These plaques are given as gifts normally to Officers or Chief Petty Officers after a 2-4 year tour on the ship or sub. They are normally mounted on a wood plaque with a name plate for the person it was given to, These did not have wood plaque??

No, no plaque. They came from a man I believe was involved in decommissioning these vessels. Thank you for the insight, that is a wonderful collection you have going, much respect
