The question refers to a letter apparently having the C6 format (4.5 x 6.4 -

It was sent from and to New York City.

I wonder:

- Why was it franked twice, at two different dates?

- Why are the rates different?

- Why has the value on one metering stamp 3 leading zeros and it has only 2
on the other (maybe different postage meters used)?

The scan of the right side (about 1/3) of the letter, zoomed, is shown he

To start , the two meter impressions came from two different types
of Pitney-Bowes machines.

On two different dates. Perhaps the envelop was part of an earlier
mailing, but misfed to the machine, and pulled out to be reused. Perhaps
someone was unsure if upside-down markings are valid.

Could we see the whole envelope, please?
This might give us some evidence as to the rates.
