How can I tell if a coin is rare?
I'm interested in delving deeper into the world of cryptocurrency collecting, but I'm struggling to determine which coins are truly rare. Could you offer some guidance on how to identify a rare coin? Are there specific metrics or factors I should be looking at, such as the coin's age, issuance quantity, or its demand on secondary markets? I've heard of certain coins having limited mintages or being only available for a short period of time, but how do I verify this information? Additionally, are there any tools or resources you recommend for tracking the rarity of coins?
