Do coins from item boxes count towards total coins collected?

Mario Kart 8 has coins scattered about the track which make you go faster and contribute to unlocking kart customisations. Coins can also be obtained from item boxes - there's one item that gives you 2 coins when activated. These (obviously) contribute to making you go faster, but do they contribute to customisation unlocks?

Solution 1:

Yes.

The number of coins added to your total is the number of coins that each local player has at the end of each race. Regardless of how you collected a coin, if you have it at the end of the race, it counts.

For more details see the Mario Kart 8 Total Coins Collecting Logic question.

Solution 2:

Yes.

All coins contribute to item unlocks, including coins from item boxes.
