Based on its design, colors, and dimensions, this is a
1914 Ohio motorcycle license plate.
Here are the specific details that identify it:
- Jurisdiction & Year: In 1914, the state of Ohio issued motorcycle plates with this specific orange-on-white color scheme.
- Design: The "OH" stacked vertically on the left was the standard abbreviation used by Ohio for motorcycle plates during that era.
- Material: These plates were made of porcelain-enameled steel, which gives them that distinct glossy, heavy finish and embossed look visible in the photo.
- Size: You can see from the ruler at the bottom that the plate is approximately 8 inches wide. This smaller size (compared to a standard 12-inch car plate) confirms it was intended for a motorcycle.
During the early 20th century, license plate colors changed every year to help police quickly identify if a vehicle's registration was current. These porcelain plates are highly collectible today because they don't rust or fade as easily as the stamped metal plates that followed.
