The first piece in any collection is rarely the best — it's the one that taught you how to look. Whether you inherited a box of grandma's silver or you're walking your first estate sale, the same instincts apply: examine the object, ask what it's made of, look for marks, and trust the small details over the dramatic ones.
Start with a category you can love. The best collectors specialize. Pottery rewards patience, jewelry rewards a loupe, furniture rewards muscle memory for joinery and patina. Pick one. Read about it for a week before you buy anything.
Build a research habit before a buying habit. Use sold listings — not asking prices — to calibrate value. Cross-reference maker's marks against multiple databases. When something looks too cheap to be real, it usually is.
Condition trumps almost everything in resale value. A pristine common piece outsells a damaged rare one nine times out of ten. Learn the difference between honest wear (good) and harsh restoration (bad).
