On July 1, 2017 the metal composition of the 5 cents changed into a steel core with a copper overlay and the 10 cents and 25 cents changed into a steel core with a copper-nickel overlay, which makes all these coins magnetic.
Because of the metal composition change, this coin will have a new KM number. Although it's likely to be KM# 30a, 31a and 32a only Krause can assign a KM# number so we have to wait till Krause officially assigns this number to the coin and unfortunately this could take a few more years.
Since this change took place in the middle of the year it's likely the 2017 coins exist in old and new metal composition, so be aware to tick the right entry when adding a 2017 coin, especially since there are several other entries between the old ones and the new ones. And those who already added a 2017 coin, please check if it's non-magnetic or magnetic.
