I know that it's not easy to believe, but you can find some extremely valuable items in storage units. In just the last year alone, I have found gold in storage units four times. The first time, I hit the jackpot. There was a safe that contained 5 jewelry boxes full of gold jewelry among other things. Two of the times I found a single piece of gold jewelry and another time, I found a small jewelry box with about seven gold & diamond rings in it.
That same year, I found 2 shotguns, a rifle and an antique pistol from the 1880's. I have found some cash a few times but in most cases it was less than $300. I have spoken with people who have found larger sums of cash in storage units that contained illegal drugs. I have even spoken with someone who found a skeleton in an ice chest. In situations like these I recommend getting the proper authorities involved.
The moral of the story is that you never know exactly what you are going to get and that you have to take the good with the bad. But, if you are persistent, you can acquire some incredible possessions and at the some time make a healthy profit reselling items purchased at auctions.
Absolutely you can find items like that. Just last night I was processing a unit I bought up near the Port of Houston. I paid $10.00 for a 10×20 unit. It was what I call an apartment unit. We found 2.1 ounces of 10-14kt gold jewelry in just one box. Scrap value right now would be about $1,300.00 and melt value is about double that. You never know what you will find or at what facility you will find it.
