Stamp values

Note: This is an old post in a blog with a lot of posts over a long span of time. The world has changed, technologies have changed, and I've changed. It's likely this is out of date, the code doesn't work, the ideas haven't aged well, or the ideas were terrible to begin with. Let me know if you think this is something that needs updating.

The United States Post Office increases the cost of postage periodically. They do faster than I use the stamps that I've bought. In the process of this, I ended up with first class stamps that have no value listed on them, so I had no idea how much they were worth.

Buried on the USPS web-site is this quick service guide that lists the values of all stamps that have no value listed on them.
