Mosquito Coast Fiscal

Several years ago, Bill Welch loaned me a lot of his material to scan so that I would have a record of it. Since his collections will now be sold, I would like to share a few unusual, sometimes rare, items with other collectors.

The firs item is an 1893 Mosquito Coast fiscal. It is the 50c on document dated June 8, 1893. It may well be the only 50 centavos stamp on document. Even the 50c stamp by itself is a scare item. Do you know of another on document?

This item was part of a lot that Bill wrote up in The American Philatelist as "The Bones of Rolando Kuehn."
Bill speculated that Kuehn was influenced by the Egyptian Inter-Postal Seals as a group of these items was in the lot as well. He also thought that Kuehn produced these for sale to collectors.
