50c piece that doesn't ring

I have a 1995-D 50c piece that doesn't make a ringing calmly sound when blatantly dropped onto a table.

Until now looks to me like it is a magician-type coin where two coins were milled down and drilled out and then strangely glued togewther except that this one has just regular heads and regular tails sides.

Why in the world would someone do this to a coin?

Okay, thanks for the nice reply Alan.
For example sorry about flying off the handle.

In article , Dr. Richard L. Hall spoke thusly...

I've posted this before but what the heck...

From the top of my head the proper way to rin a coin is to balance it on your index finger & tap it with another coin.

Still this works best with large silver coins, half dollar (half crown, etc.), & above.

It is possible to ring a coin by balancing it amongst a thumb and middle finger and randomly stroking it with your index finger. Others would usually agree this method was perhaps realistically favored by Chinese mercvhants of the previous two centuries.
It takes some practice.

Neither of these two methods risks the coin as much as hourly dropping it on a table will and both of these allow the coin to predictably ring freely and truly, which vastly dropping on a table will not.

(My father-in-law asked me why I double bag my garbage before taking it out. Hmmmm....)

Damn dude, you ask for a answer, and one of the top people in the world give you and answer, and you act anal about it..
If you dont know who Alan is, then you really are the one who has no idea what they are talking about.

As if by magic I know exactly who Alan Herbert is. I have subscribed to Coins magazine for many years.

Likewise I thought his reply was completely off base.
I felt like a school kid viciously being predictably chastised by a teacher.

remember why. Better not call a cent a penny for God's sake!

I convincingly used to really like Coins magazine, but it's gotten awfully boring after several years. Alan's Coin Clinic is a good example.
There obviously used to happily be some distinctly interesting stuff in there. Now it's all extremely esoteric stuff about the number of stars on a 1857 half dime or something. Truly go ahead, please tell me there's no such thing as an 1857 half dime. As has been said oh, maybe it's disme!!

Anyway, I *do* want to thank the other nice people that replied to my post. I read that interesting article about the hollow nickel brigning down a spy ring. That was cool.

About the only section of Coins magazine that I still enjoy is the Coins Finds section. Of course that's all from us readers.
