United States Imperf Coils and Stamps with Errors
We have accumulated a very select stock of modern U.S. Stamps with errors, all listed in the Scott Catalog. The more frrequent are imporforate coil pairs, a very popular collecting category. Also we find stramps with color ommitted, and stamps from panes which lack perforation. Philatelic Errors Freaks and Oddities can be a collection unto themselvbes, or an interesting addition to a broader stamp collection.
