Is it just my eyes, or do the features on zincs, especially the dates, wear down a lot faster than on coppers? Or is it just that the zincs aren't stamped as deeply? Or is it both? It seems like a lot of the dates on coppers seem more prominent than on zincs. Then again, isn't zinc softer than copper anyway?

| Zincs aren't stamped as deeply. I think they aren't stamped deeply because then the zinc would bleed thru the thin copper layer. On copper they didn't have to worry about that. |

| I also seem to notice that most of my corroded cents, turn out to be zinc. |

| There is a very distict differance in 1970's Canadian Copper Pennies vs modern Steel and Zinc Pennies (Cu coated). I can spot the 70's coins without seeing the date because they are stamped deeper/more relief. The modern pennies are not pressed as deep or hard. I agree with Tourney64 - might be because of the plating. |

| Agreed, the coppers, especially the rims, seem to wear much better than the zincs. |
Are you throwing that out? |

| The zincs have a definitely lower relief. I've also noticed they do seem to be the majority of corroded cents, for some reason especially 1984s. |

The Mint has been very gradually reducing relief on coins in order to squeeze more life out of their dies and presses. I think the amount of relief in a coin is inversely proportional to its circulation life; in other words, a low relief coin won't live as long as a high relief one. There comes a point when lowering the relief too far will result in more coins being needed to replace the less-durable cheap ones.

Heh, i'm glad to see i'm not the only one who thinks that the new Washington portrait looks ridiculous.
i've noticed that the weak strike problem seems especially bad on 1998-2002 pennies, and that the mint improved things a bit after that. A lot of the Y2K pennies in particular look like they were just sketched on the planchet with a pencil.
For some reason, i get a surprisingly large number of zincs that have partially dissolved... i've had some that were missing a good 15-20% of the metal. |
Nothing of value is an investment unless you possess it. If all you've got are paper, pixels, or promises, you're gambling. |
