The Lynchburg CD 112 was created from reworked Brookfield CD 102 molds (see The Origin of the Lynchburg CD 112).

CD112 retooling

As a result, no two molds are exactly alike, a feature shared with Lynchburg's CD 252. There are minor differences in the shape of the dome, the width of the upper wire groove and its shape, as well as overall height. One mold (MOLD 5) is about 2mm taller than the others. Since these variations are unique to each mold, they are not considered different types.

Comparison of different sizes of Lynchburg CD 112 molds, from the left: Mold 5, Mold 2, Mold 4.

All lettering on the molds is hand engraved. It is uniform and in the same style, suggesting that the lettering was all done by a single engraver. On most of the molds, the 1 of 31 is engraved at an angle so that the edge slopes to the right (see below). All of the molds have either 01 or XO on top of crown.


Arrow points to sloping edge of the 1.

This style does not occur in smooth base. There are a variety of base collars used on CD 112s, resulting in different drip points even on a single mold.

Example of various base collars used on a single mold, here Mold 1: CDP:sm (left), CDP:n (center), NDP:b (right).

There were 175,532 of these made between January 7, 1924 and March 28, 1925 (see below). This total may not include clear and clear tinted pieces (see Birmingham).

Most Lynchburg molds were made in sets of either six or 12. However, there are only nine confirmed molds of the CD 112. There are 5 of these molds that have been confirmed without a mold number (made before the mold numbers were added). All 9 molds may exist without a mold number.

Molds below in gray may exist but have not been confirmed.

* while the Price Guide lists molds without any crown lettering, all nine molds of Lynchburg CD 112 have either an XO or 01 on top of crown. These crown markings were a feature of the original Brookfield CD 102 molds from which these were made. The crown markings may be indistinct on some pieces made later.
