Add as many to the list as you want! I'd definitely separate Czechia (the new name) from Slovakia and Czech Republic. Good luck with South Sudan! Do they even have a currency yet?
Hi! Welcome to Coinpeople! There's probably nothing unusual about your coin - just an old worn coin (you'd look like that if you were shuffling around for 82 years!). Best case scenario for you - the die used to strike the coin was worn or partly filled with grease when it struck the coin leaving an incomplete mark.
Very cool! I have so many questions!
- What sort of profit margin does a coin dealer expect?
- If I have a completed series, does it have any more value than the individual coins added together?
- What are some of the "holy cow!" coins or notes that have passed through your hands?
