This H&B logo center brand is identical to the previous label but the Registered Trademark symbol is added to the right of the "H&B" logo. he "Powerized" process was patented by the Hillerich & Bradsby Co. Beginning in 1935 until present, they go with just "Powerized" The Powerized" process is to harden the surface of the bat much like the bone rubbed finish of the 1920's.
Ch'in existed as a feudal state under the Zhou since before 1000 BC, casting coins (currently listed under Zhou) from about 400 BC.
Traditionally we refer to the Ch'in Dynasty as beginning in 255 BC when the Ch'in conquered the Zhou.
This is a reference guide to the cast coins of China, not a listing of coins offered for sale (although a listing of examples we currently have available can be viewed on our : our vcoins store.
Images represent the types and may be larger or smaller than the actual coins.
Some date it to 221 BC when they finished unifying China (note this unified China was much smaller than the China we know today), but the Ch'in themselves probably would have used a date of about 325 BC when Duke Hsuan Wen adopted the title of Emperor after defeating the state of Wen and withdrew Ch'in allegiance to the Zhou.
