Mexico 1887 10 Centavo KM# 403 - Fake? Rare? - Bronze

The coin you have posted is a contemporary circulating counterfeit. It was likely silvered to pass. The core being brass or bronze points to a late date 1890s or so. There was a large hoard of these types discovered in the late 1990s. That particular group of counterfeits had been stripped of the majority of silver plating in a refinery. The "off metal cores" were disposed of in a dump and it is that dump which was discovered.

The hoard contained VERY FEW examples from the early period and as far as I have been able to determine no Riddell examples at all.

The type is rather common (perhaps in the 100s of examples per date) with many repeats of the identical dies. Most are well worn as is your coin. The die style appears close enough to original to have been created through some sort of transfer process.

The type rarely brings over $5 to $10 and there are fewer collectors of the decimal counterfeit series than the earlier reale series.
