An interesting and though provoking question for sure! I like all types, whether a coin, round or bar. However, I like the western theme or Native American thing. I also am wondering if there are any silver rounds or bars referencing coffee or coffee beans? I did a quick search and turned up nothing, but didn't spend a lot of time or effort yet.
Coins are interesting because of the history aspect of the coin. The older, the better. So, Secret Santa, I'm open to anything really cool, but really would love a coffee themed round, bar or coin, if there is such a thing! However the Western/Native American thing works well too!
Thanks for the question @welshstacker! Take care and have a lovely day!
