| PG&E nails are found in Northern California. The earliest date found is 1922 (though some old timers claim they have been in use since the very early 1900's) and they run up to present day. All are steel nails, with mixed Raised and Indent numbers with the exception of the 1981 which is aluminum. For more information you can check out Rolland Meyers article on PG&E Nails |
