many things to consider..1990's gold eagle just sold for $36,000+!!

I believe the time to invest in some 70's is too late.The past few years have seen hundreds of perfect 70's in population reports for every denomination..with many still uncertified I'm sure.The prices are relatively low for most though but with high pops probably won't see a great jump for a while.The 69's may increase at a higher ratio for these coins.Many coins of the 1990's have pops less than 50 as perfect 70's and still can be found for $300 or less..a great investment I would guess as not many more will surface.With increasing popularity of the registry ranking system, the 70's will always be in demand.For a non-registry coin{one I buy for owning and not points}I go with the 69's too....Kinda off the subject but am I the only one who notices that AU58 coins are more often much more eye-appealing and over all nicer coins than their MS60-62 counterparts? They may have only the slightest/almost undetectable rub and then must be virtually scratch free with outstanding luster and strike..whereas an Ms60-62 often is dull with even scratches or marks evident in prime focus areas like cheeks/face/eagles etc..and/or weakly struck...any thoughts on this from others who agree?
