Hey everyone. I'm well on my way to putting together a non key date Morgan silver dollar collection (no CC's, 1895, 1893-S, 1894, etc.) and I noticed that some dates show a consideral jump between EF-40 and AU-50. Specifically some of the dates I noticed are 1892-S, 1896-S, 1904-S, and some others. What would be the reason that these date don't have as many survivors in AU to MS condition compared to most other dates? Were there not many of these in the GSA hoard, or is it a case of those dates/mints have notoriously weak strikes and goods example are hard to find? The reason I ask is that nearly all of my examples are AU and I figure I'll have to add some XF examples to complete my set. Thanks.
Since supply and demand is what determines the value of any given coin in any given grade the obvious answer is that the coins just are not readily available. One possible explanation is that large numbers of them were melted.
