Colorado 1913 Porcelain Plate
1913–1913Colorado · annual
Colorado's first state-issued plate, and one of only three the state made in porcelain before switching to painted steel. COLO reads up the left edge and the year up the right. Porcelain gives a glassy, saturated black that no painted plate matches, and chips to bare metal the moment it is struck, which is why so few survive intact. The plate shown is a reconstruction carrying an invented serial, so no real registration is depicted.
A plate for one year only
Colorado replaced its plates every year in this era, which is why 1913 is stamped into the design rather than carried on a sticker. The plate was the registration: it was surrendered and replaced twelve months later, and the colour pairing usually changed with it so an officer could date a plate at a glance. That is also why plates from these years are scarce, each one having been current for a single year.
Before the standard
This plate is long and shallow rather than the familiar oblong, roughly 13.4 by 5 inches. The uniform 6 by 12 inch size was settled later through the American Association of Motor Vehicle Administrators, and until it was, plates were sized to each state's own taste. That is why one of these will not sit in a modern frame.
Stamped, not printed
Every character here is pressed into the metal and stands proud of the surface, along with the raised rim just inside the edge. Run a hand across it and you feel the whole design. The plate was struck from flat stock in a press, then the raised faces were rolled with paint, which is why wear shows first on the tops of the characters.
