I have a TB, 30 and Out, that has gone missing in the USA. I've given it 6 months or so and it has not re-appeared, I've contacted the placers and 6 or 7 of the next finders of the cache it was in to see if any picked it up and just forgot to log it, all with a negative result. It was originally released to coincide with completing 30 years in the police and so has some meaning to me. I have decided to replace it with an exact copy. The question is this, should I use the COPY TB tag and adjust the mileage or should I be getting a new tag and starting again? My guess is that there are no hard and fast rules on this and it is what I feel comfortable with.
