How About This, What's The Best Way To Prevent A Crime?

A couple wise old sayings come to mind ....

"Discretion is the better part of valor" and "Loose lips sink ships"

You may tell your friends that you collect coins, but you don't need to tell them that you have an extensive collection of rare and valuable Double Eagle Gold Saints. Operational Security is very important. the more people you tell about your fabulous coin collection, the more people that know about your fabulous coin collection. That guy at the coin show seems like a really nice fellow collector. But, his method of collecting might be a little less legal than your method of collecting. Don't make yourself a target.

The best way to prevent anything from stolen from your house is
to not own anything valuable.

Not long after we were married, the things most near and dear to me was my wife and kids.
Now, sadly I am a widower, but my kids are all quite happily married, and I live alone.

I do, however have a moderately valuable coin collection.
That requires a far less level of care and protection than my wife and kids ever did.

A gun is certainly something I don't need.
