Maybe the copper-nickel coin weighs differently.
There are other tests -

which can be found on the forum.

A lot of these [various years] say copper-nickel [for that denomination] is only 26 g weight ...

So, how to add this coin in the copper nickel category, there is no copper nickel category available in our numista database.
