Here in New Jersey, any plate issued since 1959 is still valid, and can be used on the road. For various different reasons, plates can get replaced with the same number if , for instance, the plates are lost or become damaged. Thus, the "remakes" page.

Remakes on the   2007   Graphic Base
These have no sticker boxes. Anything lower than VZx- on this base (with some exceptions) qualifies.
Remakes on the   2004   3M-2 Graphic Base
This is something we will probably not be able to spot on the road, as the Avery and 3M-2 bases are vitrually identical.

Remakes on the   1969   Reflective Base
Another really tough find. This would be a plate with a number between AAA-100 and RHZ-999 on the '69 reflective base. Nothing here, either.
Remakes on the   1959   Base
This would be an interesting phenomena - I suppose that the only way to verify a set of '59 remakes would be to find more than 2 of the same plate number. Needless to say, I have nothing in this category.
