My father recently gifted me some of his collection from the 70-80's. He wasn't too serious, but he gave me some of his old Whitmans with dupes in them. Has some nice hole fillers for me. The coins have been in there slightly longer than 30 year. They all look to be in surprisingly good shape excluding the steel pennies which rusted around the edges. One thing I saw was a shiny silver colored 1955 LWC. I still need to weigh it and check it for magnetism, but I'm assuming it's post-mint. If it is PMD, it happened sometime last 70's/early 80's if that makes any difference. I cannot stress how much I do NOT expect it to be anything of value. However, I'm still curious as if there are any remotely plausibly scenarios that I could research. E.g. dime planchet, maybe some weird foreign planchet or something. I don't know too much about that stuff. Sorry, my camera is dead. But the size of it appears to be normal. Working on a weight and mag test this evening. Edited by trent

Size,weight and pictures are a must if you want good answers.Magnet test is always nice too.Wrong or foreign planchets are always possible but we will wait for more info  |

I have one from 55 also that is thinner and sounds similar. Have been told acid bath which don't think was. Also been told thin planchet. Mine weighs 2 grams right on. Curious see what urs looks like and weight of urs.

Verifying weight is the key to these mysteries. My friends and I achieved similar results in chemistry class by dipping the coin in mercury.

I have a similar 1955 LWC, silver colored. I assume PMD. Maybe I should check. Interesting that it's the same year, though. Same with iowaguy. |

This is a chrome plated coin, the type used on Door Knobs   |

It is magnetic. It does weigh 3.1g but my scale only goes to one decimal place. It did display 3.2g for a quick moment before settling back down to 3.1. Upon further inspection the plating covers both sides of the coin but does NOT cover the rim. The plating goes right up to the edge but stops before covering rim. In one very tiny spot the coating does drip down to the rim exposing the sloppy plating job. The rim of the coin appears to be copper like a normal penny. Now I'm even more sure it's PMD. Am I right? (sorry camera still dead) |

What common metals are used to coat a penny that would be magnetic?
It's not nickel, silver, or zinc. Google says chrome, platinum, and mercury aren't magnetic either.
It could be steel but due to the way it was stored, I'd expect it to rust like the other 1943 steel pennies that were rusting in that binder. Is there anything else it could be besides steel?

Didn't know that thanks. So it looks like the tossup of nickel v. steel.

You don't normally (and I'm not even sure if you can) plate with steel, but nickel plating is common.

Good point, and would it be correct to assume nickle doesn't rust? Because the other steel cents next to this in the binder rusted right up, if this coin wasn't rusted, odds are looking like is was not steel but is nickel plated.
