Scrimshaw Whale Tooth

I've been very curious for years about the possible value of this piece of Americana. It is a genuine whale tooth, approx. 4.5" tall. It has several unusual features not seen in a typical item of scrimshaw. While most carved whale teeth feature a nautical theme, this is literary. The portrait of John Greenleaf Whittier as a young man is carved on one side; on the other are three stanzas form his poem "The Eternal Goodness". Above the poem is a star inlaid with what looks like abalone and the name "Sarah" within. Around the top is a whale hunting scene and the tooth itself is mounted on a custom made brass base. Near the bottom on one side is the initial "D". Both red and black inks were used to highlight the carving.
