This set is the "baby gift" version of the regular BU set for the year, and contains the same coins but with gift packaging.
The Mint says about it:
"The birth of a child is surely one of the most precious moments in the life of any parent. The Münze Österreich Baby Euro Coin Set is the ideal memento of the wondrous Occasion.
Containing all eight euro coins minted in proof quality, the set comes gift-packed in a charming booklet in which you and Peter the Bear can tell the personal story of your new family member. Children love hearing about the first steps they took, and this booklet is the perfect place in which to document that and other landmarks in your child’s development."
