Start with the obverse. A genuine Puebla 20 centavos of this type shows a profile bust as the central device. This portrait element sets it apart from the plainest revolutionary coppers, which carry only numerals and an eagle, so confirming a deliberate profile bust is a useful first step in attributing the coin.
Turn to the reverse and confirm two features together: a large numeral 20 marking the twenty-centavos value and the Mexican national eagle with spread wings. The bold numeral, rather than a small mark tucked into a busy field, confirms the denomination. Because the eagle appears on a great many Mexican coins, do not stop there; read it alongside the numeral, the date, and the Puebla attribution rather than treating the eagle alone as proof of type.
Check the date and the state reference. This issue is dated 1915, which places it in the Mexican Revolution, and it is a State of Puebla product, so inscriptions referencing Puebla and the centavos denomination are part of the identification. Reading the visible legends and the date, even where wear has softened them, helps separate this coin from other revolutionary coppers of the same era.
Confirm the physical characteristics. This is a copper coin, so expect a brown to reddish or darkened surface and a modest, low-value module. The look is typically a bit crude, with uneven strike and occasional off-center design, because revolutionary coins were made locally under difficult conditions. Honest wear softens the high points of the bust and eagle evenly; weak spots from an incomplete strike are normal and are not the same as damage or tooling.
Watch for look-alikes and reproductions. Many revolutionary authorities struck eagle-and-numeral coppers in this era, so a similar-looking coin may belong to a different state or issue; rely on the Puebla attribution plus the 1915 date, the numeral 20, and the profile bust to be sure. Be alert to cast copies, which can show seam lines, a grainy or bubbled surface, or soft, blurry lettering. For any valuable example or a coin whose surfaces look suspicious, seek an opinion from a specialist in Mexican revolutionary coinage before buying.
Frequently asked questions
What is the fastest way to confirm this is a Puebla 20 centavos?
Look for the profile bust on the obverse and, on the reverse, the large numeral 20 with the Mexican national eagle. Then confirm the 1915 date and the Puebla attribution. That combination identifies the type; the eagle alone is not enough because it appears on many Mexican coins.
How do I tell it apart from other revolutionary coppers?
Many states struck copper coins with an eagle and a denomination numeral in this era. Use the Puebla reference in the inscriptions together with the 1915 date, the twenty-centavos numeral, and the profile bust to separate this issue from similar coins of other jurisdictions.
Is a crude, uneven strike a sign of a fake?
Not by itself. Revolutionary coins were made locally under wartime conditions, so uneven strikes, off-center designs, and rough surfaces are normal. Concern should focus instead on cast seams, bubbled surfaces, and unnaturally soft lettering.
How can I spot a cast copy?
Look for a seam line around the edge, a granular or bubbled surface, and mushy detail that lacks the crispness of a struck coin. If the coin's value or surfaces raise doubt, have it examined by a specialist in Mexican revolutionary coinage.
