Interesting Currency from a Collection Buy
I bought a rather large collection last month and amongst the coins were a number of US and foreign banknotes (some of which I still have for sale on the WTS wink wink). Anyways, amongst the notes I decided to keep was this $10 bill from the Bank of Hanover. I am aware that local banks issued their own currency, but have no idea if anything I have is of value, if the condition would be considered poor, average, good etc. I took a look at Heritage and found a few examples of this note but with a red seal - does the blue seal have any importance? Obviously any help with a rough valuation would be great but I am not looking to sell! Additionally, as I am not a collector of notes, what's the best way of storing these? Currently it is in a Ziplock bag but that seems to be an insult to such a nice looking bill!
Thanks in advance, MJ
