Like many of the 2000 series patterns, you’ll often find a numeric notation that is likely the glaze color after the 200x number (like 2007-4, etc.). This glaze notation is unique to this pattern series.
The 2002 pattern typically features a wide outer band, middle “wave,” and thin inner band.
The 2006 pattern varies by piece. Plates and patterns feature a series of thin lines. The creamer / sugar combo and gravy lines alternate colors. These pieces are marked either 2006-4 or 2006-2. As with other decorated patterns, smaller pieces may not be marked.
2007 patterns have two big fat rings and a lot of thin rings in the middle. Even though there isn’t variation in the pattern, the marks read 2007-1, -2, -3 and -4.
The 2008 pattern includes a dual wave and dot design with an outer solid ring.
2009 is close to the 2008 pattern. The second wave/dot is on the inner part of the plate and there is no solid outer ring.
