So I have my Dansco albums for Lincolns(1909-date), Morgans 1891-21, peace dollars, mercury dimes, ase, and my US type set. My question is this, what coins right now are the most undervalued? I wish to have a complete US coin set someday and know some are harder to obtain than others. Ive noticed higher grade Barber dimes selling cheap on eBay, was thinking of starting there. I'm not rich by any means so I know the seated/bust dollars are out of my range and don't know if I want to do a Roosie or Washington set just yet. Opinions? Looking to complete VF+ sets.... thanks everyone.
