Case in point:

A good friend of mine bought an entire collection from the estate of a fiend of his who had passed. The widow had the collection appraised, and my buddy stepped in at the last minute and bought the stuff from under the nose of the appraiser/broker.

The widow received the same amount as had she sold it to the broker they screwed out of the deal. The lot was $25k, +/-. You might say the original guy didn't have a good strategy.

My pal sat on the stuff another 15 years, until he reached about 80 years of age. He then sold it off, one by one, on Gunbroker and netted near $50K. Most of the value was in Colt pistols and Winchester rifles.

He had a better strategy.
