According to this link

From the link above…
Between 1835 and 2016,The Osborne Coinage Company went through a number of name changes including the following: 1835 - Z. Bisbee Co. 1848 - Z. Bisbee Son 1851 - Bisbee Stanton 1852 - John Stanton 1864 - Murdock Spencer 1869 - Jas. Murdock, Jr. 1906 - The James Murdock, Jr. Co. 1920 -The Osborne Register Co. 1947 -The Osborne Coinage Company, Inc.
From their Osborne Coinage Co. website…
From the link above…
Z. Bisbee Co. – which eventually became The Osborne Coinage Company – America’s Oldest Private Mint
Going through many trade names in history, from Z. Bisbee, Murdock, Osborne Register and finally Osborne Coinage Co.
I think that Osborne Mint is incorrect and based on the mintmark that changed from OC to OM. Osborne Coinage Co. name has stayed the same since 1947, just the mintmark changed.
So, Based on the above information can we add:
Osborne Register Co. that began in 1920 to 1946
Based on these tokens
And move Osborne Mint mintmark to Osborne Coinage
Osborne Coinage began in 1947

Edit: It appears that it is two separate companies at the same address. I am incorrect about moving Osborne Mint.
