Hi everyone! I recently picked up this pen that I believe to be from the civil war era. The nib says "John Foley's Bank Ben New York No. 7" I have seen varying versions online, but they all have a date on the nib; this one does not. Is that a problem? This does seem to be from the civil war era, but again, I am not an expert in this. I'm looking for more information on this such as when was it made, if it is okay that there is no date on it, what is its worth, that sort of thing. Any and all help is much appreciated. Thank you! Pictures can be found here because they are too big/too many to upload https://drive.google.com/open?id=1RuRTQbTIIVBUo-FK_QZFKnIdYjC7RXjJ
