The King Charles shape had a rather short production run. Forty-six patterns first appeared in the 1903 pricing catalogs. By 1905, there were 75 total patterns, but that number decreased over the next two years with 58 in 1906 and 45 in 1907. By 1908, King Charles was no longer listed. Like most other HLC shapes from the very early 1900s, King Charles was eventually overshadowed by The Angelus and Hudson.
The distinctive flower/chain embossing was not used on any other HLC shape which makes identification easy. It is generally marked with the eagle over lion backstamp shown or with a simple Homer Laughlin-King Charles script marking.
Although the line was offered for at least five years and had an extensive assortment, examples are somewhat hard to find. By contrast, other shapes of the day (namely American Beauty and Colonial) are somewhat common.
