Now that you're prepared, it is time to get to work. Set your alarm because the early bird gets the worm, the Mickey Mantle baseball glove and the mint Atari 2600.
Be ready to hit the first sale around 7 or 8 AM. Have a couple hundred bucks on you in small bills. When you haggle the price down from $50 to $20, it's awkward to ask for change for a crisp fifty.
You won't be the only one at the sale digging for treasure, so be decisive. If you're not sure if you want an item, carry it around the sale while you look up the value. Don't turn your back on it.
Have boxes and protective packaging. You don't want to find a valuable vase only to have it shatter in your trunk. Make sure you bring a vehicle that can accommodate a big score. If you think you will snag a table saw or a lawn mower, bring the truck.
Don't be afraid to ask questions. Get the story behind vintage items. It will add value when you sell them later. Have the seller plug in electric items to be sure they work. Look into the battery compartments of electronics and check for corrosion.
If you're hunting for jewelry, bring a scale. You may be selling the items to be melted down. Know the value of gold per ounce and use that to determine your offer.
