What is the most overlooked item at garage sales?
Vintage cameras and film equipment are consistently underpriced because sellers rarely know their value. Cast iron cookware (Lodge, Griswold) is another category where sellers price by weight rather than market value.
How do I quickly identify an item I do not recognize?
Use Google Lens to identify the item by photo, then check eBay sold listings by model name. Or use Estimatik — snap a photo and get a real resale range in 10 seconds without needing to know the model first.
Should I buy an item if I do not know its category?
Only if you can verify the value on the spot. Use Estimatik or Google Lens before committing. Buying unknown items is a common beginner mistake — stick to categories you understand until you build broader market knowledge.
