Unknown Chop Mark.

Welcome to Coin Community, dmaskman. Turn your researching focus to the Caribbean, possibly Haiti in particular. You might find this to be even more of an official stamp than just a chopmark.

The following excerpt is from an auction catalog from Dix Noonan Webb in regards to a large collection of West Indies countermarked coins:

The series of pierced dollars now attributed to Haiti have previously been attributed to several West Indian islands. The countermark has been called a pineapple and attributed to Jamaica and later Barbados; it has also been called a crab and attributed to Vieques, an island just off the south -east coast of Puerto Rico. The pierced dollars uncountermarked have previously been attributed to St. Kitts. Research by F. Carl Braun, ‘A Triple Numismatic Enigma of the Nineteenth -Century Caribbean: Haiti, Barbados, St Kitts, or Vieques?', published by the American Numismatic Society as part of the Coinage of the Americas Conference series, properly attributes these coins to Haiti and identifies the countermark as a palm tree (Hispaniola Wine Palm, Pseudophoenix vinifera) a species indigenous only to the island of Hispaniola (Haiti occupying the western third of the island and the Dominican Republic the eastern two thirds).
