Portugal, 1924 50 Centavos Bronze-Aluminum coin from the Portuguese Republic, World Coins Portugal KM#575. This coin exhibits extremely unusual characteristics and may be a unique specimen, given its singular features. On the obverse, it shows incuse (recessed) marks resulting from the impression of a mirrored reverse die. On the reverse, incuse marks attributed to a mirrored obverse die can be observed. So far, this is the only coin I am aware of that presents such features. The assigned grade is AU, and the visible irregularities are due to the aforementioned issues, in addition to die crack marks.
