Hidden "B" and "G" in rays. The initials "B" and "G", for Bernardo Georgy the lease holder at the Durango Mint, were added to the dies of the 1848 issues. This was done so for ease of identification due to high quality counterfeiting, most likely done from official dies. Since this action was against government regulations Bernardo Georgy lost the mint lease.
