I have learned a lot from my original question and the spirited discussion that ensued. Not sure if it will change my direction but let me clarify any assumptions.
1) I am not a sophisticated collector -- I just wanted to fill that next slot in my annual Silver Eagle collection, not graded.
2) The other 20 shipped in the sealed tube to be held for future . Possibly graded in the future, possibly sold as is, or broken out for individual sales.
I had some assumption that because they are US Mint issue the requirement to have assay made them somewhat more trustworthy vs having to have a non-stamped bullion bar. That certainly gets more clouded as more sophisticated counterfeits come from all over the place. I suspect even the ASE inventory are peppered or will be with impure/diluted silver if the margin was beneficial.
Thank you everyone for your more intelligent views of this market, and practical approaches. I guess everyone has a different reason to collect. I seem to straddle the "investment" side and the "artistic" side. The ASE is just a beautiful coin to own. In that regard art has a premium, and investment has risk/patience.
