They are still valid, but you have to add additional postage to make up the 44 cent rate. Unless they are the Forever Stamps, in which case you can still use them for up to an ounce of First Class postage.
If the stamps is a forever stamp ( says "forever" on it and show the liberty bell),
its value automatically increased to the new rate and it is still pays 1st class postage.
Otherwise, it is only good for the amount it sold for and you must make up the increase with additional stamps.
There were no stamps in 1801. The first postage stamps were issued in Great Britain in 1840. It was several years after that that German issued postage stamps.
The same as stamps in other years.
The first is that the person can no longer be living. And it has to be more than ten years since the death, though an exception is made for presidents.

Yes it will be delivered. That would be enough postage for two ounces at today's rates. US Postage stamps haven't been devalued in over 100 years.
The cost of postage stamps have been carefully regulated for hundreds of years. The official US Postal Service website presents stamps in hundreds of styles and denominations.
All stamps issued by the US since 1864 are still valid for postage at their face value.
Yes, you certainly can! In the US, and most countries, stamps do not lose there value, particularly if they are less than a few years old. And as long as the combination adds up to or exceeds the necessary value, they can be combined.
Since in the last several years the price (of postage as well as goods in general) has risen so fast, the price of a stamp has changed often. This has made it difficult to plan on buying stamps, adding a two- or three-cent stamp to make up the difference when using up stamps bought before the last increase. With the "Forever" stamp, you can buy a supply of them, and you don't have to mess around with additional stamps to make up the difference.
The rate went to five cents on January 7, 1963. It was valid for 5 years.
The prices of stamps changes quite consistently over the past few years. In order to stay updated, I would visit the USPS website to see current prices for postage stamps.
