My experience, is that Generics', low premiums, usually, don't change much, thru the years. Where Government coins do. For example, in 2014, I picked up the Australian Crocodile for $18 (sale, $16 + $2 premium.) The next year, the series 2, 2015 Australian Spider was about the same, $18, but the Crocodile, was $31, same company. The generics' was and still is the same premium ($2) price. Many other similar examples. Many bullion Gov't coins double, triple ... Generics usually don't. I like that Libertad, too.
