I've noticed that common one ounce American Gold Eagles frequently sell for approximately the same price at many dealers as common date $20 Liberties in about VF condition. One-half ounce AGEs frequently sell for about the same as common date $10 VF Liberties. This approximate relationship seems to hold up for many years if you glance through some old Redbooks. I know they don't contain the same amount of gold, but is this considered a "normal" or correct valuation? For the same price, which would you prefer? Would VF Liberties make a decent bullion-type investment alternative to AGEs? Thanks in advance.
