Brick red well-formed crystals. One of the larger crystals may indeed be formed with an intergrowth of Quartz, much like feldspar and quartz typically found in pegmatites, such as this locality. The Brown Derby pegmatite is a rare-earth pegmatite with besides Monazite also has Euxenite, pyrochlores, microlites, pollucite, Col-Tan, srtibiotantalite and alot of other good pegmatite minerals. I do not know if this Monzaite it at the Sm or Ce end, probably bot. The specimen number matches the label.
Any pegmatite collector should have one of these and it is a fine specimen.

All specimens form Silver Coin are subject to intense scoping for a long time. Even then you won't see everything. The four minerals identified so far on this piece are the blue cuprian Morinite, with pearly micro crystals of Perhamite, and beady dark green Dufrenite. The Chlorargyrite is not photographed, but form waxy green looking kinda cubic crystals. There is probably Kidwellinte on the specimen and leucophosphite.
