I had never even thought about that - collecting sets of 1 oz silver coins is affordable and fun as they are relatively cheap and it’s a hobby that most people can afford and spend a little on as each new design is released. 1oz gold is very expensive to be a hobby for most people. I always thought that the premium on 1/10 oz gold is too high but I guess that it’s the wrong way to think - the value of that premium is not lost if you sell or trade the coin down the track. I can see now that collecting sets of 1/10 oz gold could be attractive, you certainly wouldn’t need much space!
