I just received the Interesting Stuff catalog of Joel Anderson (www.joelscoins.com) for summer-fall 2017 and 2 items caught my eye but not my pocketbook.
Some might argue that the Kingdom of Tavolara should be listed as a micronation instead of beinga place of fantasy after a 100,000 lire coin appeared in 2017 under its name. There are all kinds of conflicting information on the Internet but most stories are quite interesting. https://samadeleke.com/2017/07/05/tavolara-island-welcome-to-the-worlds-smallest-kingdom/
Given the questioning in the forum recently about Aruba and other countries of the Kingdom of the Netherlands,
https://en.numista.com/forum/topic61432.html, it is interesting to see that a coin (probably regarded as a fantasy) of 25 guilder denomination has appeared from constituent country Sint Maarten, picturing a KLM Boeing 747 coming in for a landing at Princess Juliana International Airport.
For those with deep pockets, German World War I prisoner of war camp and notgeld coin unique collections are offered at prices ranging from $600 to $1200.
