Switzerland 5 Rappen [Resolvido]

I was updating my trade list for the first time in years, adding the KM number where possible. I have a couple Swiss 5 Rappen coins, one of which is dated 1971. Neither Numista nor my old Standard Catalogue list that coin for that date. It seems like too low of a value to fake, and looks just like my other 5 Rappen coin from the later series, starting 1981.

Hello,

There is a 1971 date in this page for the CuNi type:

Perhaps your coin has been plated with a yellow metal to look like the AlBr type? Either way, photos would help.

Thanks - I found it shortly after posting - it was in an unexpected spot. Since Numista doesn't provide certain type variations that can be found in the Standard Catalogue (slight design changes, alignment, etc.), I didn't look hard enough.
