Let me know if you think they are reasonably priced...

Hell no.
You can go to the bank and get them at face value.
I ordered some, got sacagawea dollars, when I got home I found out that they retail for 4usd.
Susan B's are retailing at 5usd.
Go to the bank and buy all the dollar coins you can carry for a dollar a piece.
They are about 18lbs per 1000usd.
IF you buy 1000, you get a sealed box from the mint.
