1906-1915 Pennsylvania Porcelain License Plates Collection

From its first license plate issue in 1906 through 1915, Pennsylvania produced plates made of porcelain coated steel…originally it was assumed plates would be permanently assigned to a vehicle, so they were produced to last!…this group is somewhat unique as each plate is only four digits up except the one 1913, which has five…the first numbers run from 1 to 10!
