nod2003, you are correct, I too have pulled low grade Seated and
Barber coins from melt buckets as well as silver proofs. For now 90% silver coins trade by total face value and not weight, so you really don't lose anything on worn coins unless you are the one sending them to the melter.
Back to Silver Eagles. The premium is higher on these when you buy, yes, but you also get a better premium when you go to sell. I think the older dates with mintages below 10 million will also show a nice price rise as time goes on.
ASE's have also become a collector series now that there are albums for them.
I live in USA and prefer only USA bullion coins. I guess if I lived in Canada I would prefer Maples.
