The pen is a Wirt slip-cap dropper filler in black hard rubber with a gold filled "filigree" overlay. It's the sort of pen that would normally be worth several hundred, but this one carries an auction estimate of $15,000 to $25,000 thanks to engraved inscriptions that identify it as a gift from Theodore Roosevelt to Pat Garrett, including the date of December 20, 1901, when Roosevelt nominated Garrett as customs collector of El Paso. According to the catalog entry, this pen previously appeared at auction in 1996 and was shown in a book on the Old West first published in 1992.
The problem is that this pen cannot date to 1901. The nib and feed are of a form that Wirt did not adopt until a couple of years later (US patent 724984, applied for and issued in 1903), though the exact form of the feed appears to be later yet (see US patent 978420, applied for in 1908 and issued in 1910). And even if the nib and feed are not original to the pen, the trefoil pattern filigree of the overlay is a design of distinctive form that was only introduced in the 'teens -- several years after Garrett's death in 1908. What Wirt was actually making in 1901 is nicely illustrated by the 1901 and c. 1903 catalogs in the PCA Reference Library (and the latter catalog may well be later than the listed date estimate). Unfortunately we don't currently have comprehensive documentation of Wirt's offerings over the following decade or two, but since Wirt like virtually all pen companies subcontracted overlay manufacture, designs can easily and precisely be traced across the pen industry at large.
