Roman Republic, Aes Formatum, AE, Pre-coin bronze from the Roman Republic 6th-3rd century BC, Approximate dimension: 44x15x10 mm Weight: 36.57 g. The "Aes Formatum" pre-coins are small cast bronze ingots with a recognized shape, these were used as payment currency in commercial transactions between the 6th and 3rd centuries BC, they are the successor coins of the "Aes Rude" which were pieces of bronze without shape, looking more like metallic slag.

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.

Rare Variant of the 1926 50 Centavos, Reuse of 1925 50 Centavos Dies, with an Open-Stem “9” and a Foot Perfectly Aligned with the “I” of “Simões”. This study presents an extremely rare die variant of the 1926 50 centavos, until now practically unknown or overlooked in Portuguese numismatics. This variant is defined by a very specific combination of technical features: the numeral “9” has an open stem, its foot is perfectly aligned with the “I” of “Simões”, and there is clear evidence of the reuse of dies originally employed in the minting of the 1925 50 centavos, later adapted for the 1926 issue. The association of these elements, traditionally attributed to 1925 coins, appears unexpectedly on specimens dated 1926, constituting a variant virtually absent from numismatic literature. Nevertheless, its existence is now undeniable, supported by the observation of authentic specimens over several decades.
