I was recently going through my collection and I found this 3c Washington stamp. I'm still relatively new to collecting, but I believe that it is a Scott #65. It's really unfortunate if it is because the civil war era stamps seem really interesting. I'm not sure what the big black splotch is, because it doesn't really look like a cancel. It actually looks more like someone kissed the stamp wearing black lipstick or something.
Were perforation errors common in civil war era stamps? ***Title Typo fixed by Mod***
