Although this color assortment was available and sold for ten years (1959–1969), the popularity of Fiesta had fallen. Because overall sales of the line had decreased, this newest shade of green is seen as in very short supply on the secondary market relative to the other glaze colors. Both Yellow and Turquoise had been in continuous production since the earliest days, and Red had previously been in production, so on the secondary market those colors were more easily available. The last glaze color, called Medium Green was only produced during that decade, and so with less overall sales of the line, there was proportionally less product sold in this glaze color. As a consequence it has gained almost mythical status and, for certain pieces in this glaze, commands astronomical prices wholly disproportionate to the rest of the line.
