Any idea of this mintmark of Philippine 10 sentimo with different places. I look the catalog of this coin theres no such description about the mintmark. The mintmark is in the side of the letter S or under the letter S or anywhere aslong there are mintmark. What you think is this an error?
I would assume that this mintmark is placed on the die as a separate punch rather than locked in place on the master die, just like the mintmarks on American coins prior to the 1970s; as such, the mintmarks can "wander" a bit.
It is usually classified as a "variety" rather than an "error", since an "error" implies a mistake or defect of some kind is present, and there is no mistake here - just different options on "where to put the mintmark".
