Silver penny

I forgot I had this in my collection. This 1969d is silver in color. I weighed a 70d penny 2.4. This penny weighs 3.2. Any ideas? Tryed for better pics but no matter the light, it doesn't bring out the brightness of the silver.

It looks like it's been plated with something.

 

I would say it is a plated cent. Quite common,. They come in gold too.
These are a novelty thing.

 

The 70D should weigh about 3.1 I'm not sure what was done to the 69D but it was done after it left the mint.

 

Cool. Thanks all. Novelty or not, kinda cool.

 

I forgot to say welcome to CT.

 

For some reason mercury comes to mind.

 

That's not a planet anymore...

 

Did they knock off Mercury too??
Last I knew it was just Pluto but they’re thinking of designating it a planet again.

 

oops, senior moment, was thinking about Pluto.

 

Yes, if you chew on them or heat them up in a skillet and breath in the fumes.

 

My sister was is an electrical engineer. When she was in college, she worked part time building circuit boards for a construction company. To learn the process, she electro-plated a few pennies with zinc. I still have one she gave me. It looks to me like someone has done something similar to yours.

 

Yeah, in jewelry there was an article in a trade magazine in the early 90s touting how to use coins to save money in various things instead of copper, nickel etc blanks (flat thin and round metal sheets as one built up their skills). And for testing your skills at soldering, drilling, convexing, using as a buffer between some flat jewelry and the jaw clamps for soldering, light hammering (you would use the coins since they are round too to prevent overtapping (hammering) as you'd hit the coin rim if you go too far, etc.

Since the coins were still worth face value afterwards it ends up saving some money over time versus buying various sizes of round blanks, etc. Of course, now I see postings of damaged coins that could have even been from those uses these number of years later. LMAO

 

They tried to reclassify Pluto as a planet but that campaign failed.
It is a planet. It has moons that orbit it, and it is in line with our other planets and
orbits our sun in the same path. It may be smaller than other planets, but all of the rocky terrestrial planets are small. So I guess Mercury, Venus, Earth and Mars aren't planets either.

 

In a college chemlab course, we electroplated pennies with metals including zinc.

 

Actually one of the reasons it got booted (from planets of the SOLAR SYSTEM)is that it's orbit is so eccentric and not in the plane of the other planets.

 

In that diagram the orbit doesn't seem too irregular considering how far it is.
Are there any dwarf planets that are larger?
And since the sun is moving, dragging all the planets along, all of those orbits are spirals and misrepresented in that diagram.

 

The technique is called perspective. In addition to not being in the plane, look how it intersects the orbit of Neptune.
