I was looking for a series of books I read in elementary school during the mid-60’s about a young boy growing up in Australia. One book in particular dealt with celebrating Christmas at the beach and having a pudding with coins mixed in as prizes.

New format, same book stumper solving.
Betty Roland wrote a few books about a boy named Jamie. I think “Jamie’s Summer Visitor” involved Christmas and him helping to stir in the coins or prizes into the pudding.
