They won't know unless you show it to them ... unless it goes off, of course. :oops: Cal
One additional thing has occurred to me since posting is to say how to arm the alarm without setting it off. You'll need a stiff piece of thin...
OK. Here you go. A time-delay alarm for a safe deposit box. There are two circuit and one parts diagrams below. Circuit 1 is a little simpler...
Hmmm .... Gives me an idea. I tinker with electronics. Could put a small project box with a lever switch, time-delay circuit, and loud...
I think there is a difference between overpriced and high-priced. Overpriced is when someone asks more than fair market price. There is plenty...
For coins that cost hundreds of dollars and up, I consider it foolish not to buy slabbed coins unless you are very certain of your ability to...
Unless you're wanting to buy for bullion investment, I'd go for a PCGS 1913-S in MS62. It's one of the lowest mintage saints. A good buy at...

Happy New Year! :playful: OK, no looking in the Redbook until you've made your best guesses! A few rules: a. If a mint produced more than one...

Yeah. The final blow was when the owner of NWTM lost a multi-million dollar lawsuit and was arrested by the FBI for running a Ponzi scheme....
Mint NDAs, if they exist, may have a statement about national security confidentiality and criminal penalties in it for some employees. There may...

I've gotten this message before from NGC. It's happened because they've spotted something that may eventually cause damage (like PVC residue) or...
I agree with you. Anyone who thinks finders/keepers applies to historical and archeological artifacts in the US is mistaken unless they own the...
The extremely rare and expensive (six figure) original Confederate half dollars were struck at the NO mint. They were presentation pieces for...
