Found this in the case of my local estate cleanout store. I know it's not the nicest bill (wrinkled, discolored, paperclip shaped rust spot), but it's the first one I own. I'll show my ignorance and noob-ness with this question, but I'll ask anyway. Is it normal for the front colors (more of a dark gray) to be different than the back colors (green)?? I would think the color of the bill would be the same for front and back.
Yep, that's why they call them "greenbacks". Today's currency is still printed that way, although it's harder to notice now that there are background colors too. Congratulations on your first silver certificate. Let us know what you add to your collection next!
The green ink used on the backs of $1 currency notes was a lot darker than it is today. If you buy a strap of ones from the bank and flip through them without looking at the front, a note from the 1960's (or earlier) will almost always immediately stand out.
