1967 Silver Coloured Non-Magnetic Penny

Post by CaptainAdrian » Fri Mar 03, 2023 4:55 pm

I recently recieved a bunch of rolls of pennies, and I found this silver coloured one.
It is non-magnetic, and the thickness and diameter are the same as a regular 1967 penny.
Does anyone have any idea what this is?
Thank!
Adrian

Welcome to the Forum

That would be an aftemarket plated cent, probably nickel.
Technically it is now an altered coin

This coin should get an XRF, there is a tin 1967 penny just recently sold and if silver it would be worth your effort

Thanks for the reply John. I'm not sure what you mean by an "XRF". Can you tell me more about this tin penny?
Thanks!

An XRF is a non-destructive test to ascertain the chemical composition of material, primarily to determine the alloy composition of metals. Most good coin shops will have one, and certain scrap yards, but not necessarily free. I've never heard of a tin 1967 cent. They may call it that, IF there is one, due to an improper alloy mix since the normal 1967 cent is bronze and an alloy of copper, zinc and tin, with tin normally less than 1% of the alloy.

"XRF (X-ray fluorescence) is a non-destructive analytical technique used to determine the elemental composition of materials. XRF analyzers determine the chemistry of a sample by measuring the fluorescent (or secondary) X-ray emitted from a sample when it is excited by a primary X-ray source."

Look up lot# 516A TCNC auction November 12 2022 it was listed in this auction. was sold earlier in a Great Collections sale a few years ago a white tin penny 1967 Unlike this slabbed coin someone put a rather nasty scratch on the reverse probably trying to see if it was plated, most likely the scratch lost half it"s value, that is why an XRF is needed, pretend you are interested in selling this coin any larger coin shop will XRF itif they have one.

Weighing it to two decimal points would probably help to see if it is silver or not.
Silver is heavier and it should weigh more than a regular cent.

The photos showing the coin in the TCNC auction linked above, shows sign of the bronze base metal under the grey tin-like surface. I, personally, don't think that the coin is "tin", but it was the result of an improper alloy mix in the pour into the ingots which were then rolled to make the sheets from which the planchets were cut. They can call it "tin" but it's not all tin. The '67 cents were supposed to be 0.5% tin in the bronze alloy and it got away from them. Still, it's an anomaly that someone with a large wallet decided to take a chance due to the TPG verbiage write-up.

I have had this tin coin in hand in the PCGS slab, it is a white dime colour coin quite distinct from the regular penny, one would guess PCGS has XRF this coin before slab. The rest for it being a trial strike that"s a different story, the 25 cents, 10 cents and 20 dollar mentioned in the auction are all struck in nickel. The 1859 brass cent is a improper alloy mix with over 20 or so copies, yet even terrible graded ones goes for kind of crazy prices, any way a quick XRF will tell the story on this posted coin
