Mexico five centavos

2 posts in this topic

I collect Mexico five centavos 1905-1935. Looking at the census for these coins, there are none graded MS 60. Plenty of AU 58 and MS 61 etc. but no 60s.


I have the highest respect for NGC grading, but the lack of MS 60 coins is statistically impossible.


What is the reason for this anomaly?

Thank you for the question.


The absence of Mexico 5 centavos graded MS60 is not an anomaly -- in fact, you will see similar grade distributions for many other series (US or World). MS60 is actually a very uncommon grade. In order for a coin to be graded MS60 it would have to be very heavily abraded yet still show no signs of handling. That's pretty unusual, especially for a coin composed of nickel, as nickel is a fairly hard metal.


Check out the population for Morgan dollars, for example. We have graded more than 2 million Morgan dollars yet only 6,000 of these are MS60.
