I found out about it.
A full 16 Avoirdupois ounces of silver. It was produced and released
to celebrate the 75th anniversary of the sinking of the Titanic in
1987. The coin has a reeded edge and has an individual serial number.
The coin comes in a display case which has a blue plush lining and a
hand-crafted cherrywood Display chest with an insignia on the lid. The
original purchase price of this gem was $200.
