Hi all. We recently did a guide to the Mint of Poland mythology coins which has been popular and have added ones for the Moon Landing anniversary, and the D-Day 75th anniversary. Thinking about some others between now and the end of the year and wondered if there was anything that people felt would be useful. I will probably be doing meteorite coins, maybe the major architectural series now that Tiffany is close to finishing, domed coins perhaps, the proof Britannia's, and definitely a Lunar Series II guide to go with the Series I effort, but anybody have any suggestions that can be added to the list?
