Here's a good question. What's worth more...a circulated 1921 Morgan in the year 2011 or a circulated 1921 Morgan in the year 1921? A buck was a lot of money in 1921.
Well, according to: http://www.usinflationcalculator.com/ a dollar in 1921 is worth approximately $12.18 in today's dollars... I personally think that figure is a little low.
I've always heard any real morgan is worth $20 bucks....Im not sure if i'd give that for an AG or low G though, cause i really don't think im gonna be melting anything anytime soon.
What if it was a circulated 1921 small s? I don't know much about this stuff but it seems like if you were to just spend the dollar then vs. spending what it is worth now, you would get more for your money in 1921. Things are more expensive and poorly made now so even if you had more money to spend by value of the coin you wouldn't be able to get as much.
