The press is exerting many _tons_ of force on each strike. When coins are struck twice, it usually obliterates features from the previous strike. This is what your coin would look like if... Quote:

The denticles appear to be raised, but you are seeing the spaces in between the denticles that were pushed into the rim. Imagine this (since it is Christmas) - you take a dinner fork, and press it into your mashed potatoes... the tines of the fork will form the lows, and the spaces between the tines will be raised, like your "denticles" on the reverse. The pattern is the exact same as the denticles, just opposite. On some silver coins, you may see the same feature, but all the way around the coin and those may be different (clash marks of the reeded collar die). That is not possible with 1c coins, since the collar die is smooth (coin has smooth edge).

The raised area is the space between the incuse denticles from the other coin.

That area in your last pic is machine damage, the denticles are along the very edge of the die face. IMO

I don't think so, if the device had MD it would be the normal size but partially flattened.

By the way Happy New year This area is machine damaged, not sure how another coin could do that half way around the inside wall of the rim without flattening or damaging the top of the rim.  This is damage from another coin.  |
