Unlike everyone else here I am trying not to squash stampvirgin's collecting spirit
My suggestion would be that in the future always buy the best quality note you can afford. Since uncirculated $2 notes are very common
they are also affordable and worth a bit more. Stars are also affordable in uncirculated $2 notes, and worth a bit more still. In the end
you can purchase a note that is worth $8 or $10 for half that, maybe even better if your not in a hurry to buy. And do your homework.
By homework I mean buy a book about currency values, also Ebay is a good place to see what notes are going for, and so forth.
My first love (when referring to note collecting) was $2 bills and you have a nice one there.
