1. Buying without research
10 minutes on PSA Pop Reports or BrickEconomy can save you hundreds.
2. Trusting “rare” claims from sellers
“Rare” without provenance means nothing. Verify with grading pop reports and auction comps.
3. Ignoring condition
A 9.0 vs 9.8 grade can mean 10x value difference. Always look closely.
4. Buying counterfeits
If it’s 30% under market, it’s likely fake. Always authenticate.
5. Cleaning vintage items
You almost certainly destroyed value. Don’t.
6. Not insuring
Standard homeowner’s insurance caps collectibles at ~$1-2K. Get specialty coverage.
7. Buying everything in a category
Narrow focus = deeper collection. Wide focus = expensive clutter.
8. Selling at the bottom
Markets cycle. Don’t panic-sell into market dips.
9. Not tracking purchases
Without records, your heirs sell your $50K collection for $5K.
10. Forgetting to enjoy it
Collecting is a hobby first, an investment second. If you’re not having fun, stop.
