This listing is for a 1877-S Trade Box/Smugglers/Opium Dollar. These coins are often referred to as Opium or Box or Smugglers Dollars and happened most often with trade dollars. A skilled silversmith or jeweler would'empty out' the inside to make the coin a small concealable container.
They would then add a hinge so it could be closed. This insert claims that 2 different trade dollars were used - an 1878 obverse and an 1875 micro S reverse.He also included paper tabs to open the coin. It looks like this coin was hard to open as there are a number of marks on the reverse.
