23. Full plate number or self-contained marginal marking within a miscut stamp or souvenir sheet: Most often this results from a misregistered color that puts an associated plate number somewhere into an issued stamp. Another group is miscut Transportation or Flag coils that leave plate numbers wholly on top instead of underneath the design. Another involves miscuts of the 1973 8¢ Postal Service Employees issue that leaves a green plate number on the margin of the back print. These are in the curiosity class as far as value, and most examples sell from $5 to $50.
