I understand the feeling. I think it's because most are affordable in high grade. That's quite unlike the Seated Liberty type, which is in the hundreds of dollars even for a “common” date in low grade.
Many also stack the Morgans for their silver content. I noticed that an eBay auctioneer I used to follow often sold Morgan dollars in lots of 10. Well, they would almost immediately get to a CAN$260 bid, and in the closing moments, a week later, just increase by only $20 or $30…
