Sampson and Mordan, the inventors of the mechanical pencil, became the most famous, and successful, makers of high quality pencils, lasting for 150 years or so. The first patent was granted in 1822, hence the 'Centennial' name of this 1921 pencil.
This pencil is in solid Silver, the hallmarks are rubbed but still legible and date the pencil to 1921. The manufacturers marks are still sharp and crisp. The pencil has no personalisation.
There are no dings to the pencil and it works perfectly. The mechanism is a twist extend and manual retract design, as are modern clutch pencils. The twist mechanism is light and smooth.
Sampson and Mordan pencils are extremely collectable and this antique item represents a good bet as an investment as well as a beautiful, fully functional writing instrument.
