Do You Have Covers With A Large Dollar Value Of Postage?

Just saw this on e-bay, a part of a package wrapper (possibly from the Bank of Cleveland) with $768.58 in (metered) postage. Have you seen anything with a higher amount of postage/insurance on a single letter or package?

I've seen full sheets of cancelled $5 stamps ($500) that were not on a package and probably used for accumulated postage due payments rather than a single outgoing package. This piece is undated but maybe someone can estimate the date based on the older style of meter on the package.

Even the Hope Diamond package with insured value of a million dollars only had $145.29 in postage and insurance when it was mailed Registered in 1958, so this parcel with $768 postage+insurance must have held quite a substantial sum.

I own it now.

I am busy for few days before I can address how this rates as postage.

My interest is that it was sent as parcel post which cannot be registered, except in very limited and specially approved circumstances.

The Hope Diamond was only a million or so, but registration goes into the millions, fifteen or more.

Also second class matter can have postage of thousands of dollars paid. And, under certain rules, second class matter can be sent as parcel post. At which time there may be no weight limit for the sending as second class mailings have no weight limit, being exempt from the normal 70 lb limit for all other classes.

Edited for a missing space and a d. Also to say I need to examine it in person to determine was was under some of the meter strips in the upper right.

I wonder whether it was a money package.

Great! Glad that you got it, ppg, before someone else scooped it up. I was tempted to buy it because I like unusual things, but perhaps foolishly I decided not. Even that blue P.O. label itself can't be that common.
