Heritage Quiz has wrong answer

I quote from Heritage's weekly coin quiz from last week:
Last week's questions:
1. Which of the following overdates was minted in proof format only?
Correct Answer: 1883/2 Shield Nickel (25%).
My comment: Since when was the 1883/2 Shield Nickel minted in proof format only?
