Here's one from my collection, soon to be someone else's collection. It's a 1921-D VAM-1I, characterized by a broken chunk of die next to the N in UNITED. This
VAM is assigned a rarity of R-7, but in the real world it's much more common than that. Vamworld calls Condition Census 2-MS65's and an MS63; the one pictured here is NGC MS64.
Remember, 1921's tone rather differently than previous Morgans; this one I would consider "normal" toning for a 1921-D. You were talking about emerald green? I got some of that.
