The characteristics of a coddler that are used to determine the type of coddler are the backstamp and the screw threads. In many cases, we may refer to a backstamp style by the type of coddler upon which it was seen. However, two types of coddler, or two sub-types of coddler, are distinguished from one another by the combination of backstamp impression, color of the backstamp, method of application of the backstamp to the coddler, material and spacing of the screw threads, and other discernable differences in manufacturing process or visual characteristic, other than the pattern.
Type 1
Type 1 has a backstamp that consists of a shield with the words
ROYAL CHINA WORKS over the top and WORCESTER
underneath.
The
screw threads
are finer-pitched.
This backstamp is actually the imprint of George Grainger and Company. The Grainger porcelain works was started in 1801 by Thomas Grainger. The business had different names over the years as Grainger partnered with others: Grainger and Wood, Grainger and Lee. George Grainger took over the business when his father died in 1839. The company was taken over by the Worcester Royal Porcelain Company, Ltd. and was operated by Royal Worcester until 1902. The mark shown above was used from 1889 to 1902, and it includes a date code, in the form of a letter, under ENGLAND, which indicates the year of production. A for 1891, B for 1892, C for 1893, and so on until L for 1902, the year in which the Grainger porcelain works were shut down. Reference: Miller's Pottery & Porcelain Marks, p. 156

Type 2
Type 2 backstamps have C51 in a circle topped by a crown.
RW was founded in 1751, hence the
significance of C51 in their backstamp motifs.
Around the inside of the circle is the stylized W that
looks like wavy lines. Around the bottom of the circle
written ROYAL WORCESTER ENGLAND.
RW used a set of dot markings, starting in 1891, where the number of dots on either side of the crwon or among or below the words of the backstamp indicate the year of manufacture of the piece. The number of dots indicate a the year of manufacture of the piece. 1891 had no dots (the crown had a new design). 1892 had one dot to the left of the crown. 1893 had two dots, one on either side of the crown, and so on, up to 1915, where there are twenty-four dots, six on either side of the crown in two rows, and twelve beneath the words. In 1916 RW started adding other symbols and marks to the dot code. RW continues to use date coding on some pieces. On egg coddlers, it seems that they stopped using the date codes early.
Type 2A and Type 2B coddlers have a reference number, RdNo #561564 in a box below the circle. According to KM, this would be an English registry mark, and if so, the design was registered in 1909 with the British Patent Office. The screw threads are finer-pitched.
Type 2A
The backstamp is red. This mark has been seen
on a coddler with a silver lid. The example shown has twenty dots, and so
it's believed that the year of manufacture was 1911. The lid is
hallmarked 1912. (BB).

Type 2B
This backstamp is green, with the reference number
RdNo
#561564 in a rectangular box below the circle.
These backstamps have the Royal Worcester "dot code"
for dating the piece.

Type 2C
This backstamp is black. It is like 2A and 2B, without the
registration number. This example also has twenty-one dots and so
it's believed to be manufactured in 1912.

Type 3
Type 3 backstamps consist of the characters C51
in a circle topped by a crown. Around the top of the
circle are the words ROYAL WORCESTER.
Beneath the circle appears ENGLAND.
There are banners on either side of the circle
in which the words CROWN and WARE appear.
The backstamp on Type 3 coddlers is dull green in color. The
backstamp is underneath the glaze (i.e., it can't be scraped off with
a fingernail, although
we don't recommend doing this as a test, especially on an older
coddler). The screw threads
are finer-pitched.
The pedestal is often smaller than on the other types of RW coddlers.
Some Type 3 backstamps have the Royal Worcester dot marking codes, beneath the circle and above ENGLAND.

Type 4
Type 4 is actually a set of backstamps. Most of the Type 4 backstamps
have C51 in a circle topped by a crown. Around the top of the
circle is written ROYAL WORCESTER VITREOUS or just
ROYAL WORCESTER. Under the circle is written
MADE IN ENGLAND or just ENGLAND. In some cases there
are additional words stamped or superimposed onto the basic design.
the backstamp is dull green in color
and is underneath the glaze.
The
screw threads
are finer-pitched.
Type 4A
The backstamp consists of the words ROYAL WORCESTER VITREOUS
above and ENGLAND beneath the circle.
Type 4B
The backstamp consists of the words ROYAL WORCESTER
above and MADE IN ENGLAND beneath the circle.

Type 4E
The backstamp is the same as
Type 4B, with the word
FIREPROOF superimposed on the bottom of the circle.
Type 5
The backstamps of Type 5 coddlers all have
the stylized script W in the center of the circle. The subtypes
are distinguished by the words and placement of them in the backstamp
design. All Type 5 coddlers have the finer-pitched (tighter, or
older)
threads, except
Type 5E.
Type 5A
Type 5A has the W in a circle, with
ESTABLISHED above and 1751 below the W inside the
circle. Outside the circle appears ROYAL WORCESTER
above and HOTEL CHINA below around the outside of the circle.
Across the top of the backstamp are the words
MADE IN ENGLAND.
This coddler was probably manufactured for the restaurant trade.

the newer screw threads.
