How many were originally made? A low production number usually means a high price tag.
If the coin is made of silver (pre-1964 in the US) or gold, it has a "floor" value based on current metal prices. ⚠️ Pro-Tips for Beginners
PVC-free flips or hard plastic "slabs" prevent environmental damage.
Some coins are simply "hot" right now because of trends in the collecting community.
They want a physical piece of the past, like a Roman Denarius or a Civil War-era token.
This is the #1 mistake. Scrubbing a coin ruins its "patina" and can instantly strip away 90% of its collector value.
Perfect for networking and finding rare pieces from multiple dealers.
