Not an error collector, but had to get this one for my mini-collection of 1983-P quarters. How does this happen to a coin?   |

Really neat example.
This is a result of the coin being struck without the collar die to control the expansion outward.

Thanks! I thought it was a nice one too!
Does that mean that the collar is damaged or the planchet just isn't positioned probably resulting the error?

Most likely, the collar failed to deploy correctly and that resulted in the broadstrike. The reeding showing where the rims should have been look like collar clash. Both dies had made contact with the reeding of the collar and a small bit of the grooved design was transferred from the retaining collar to the dies. It wouldn't be seen on a normal strike, but the metal pushing out past the regular diameter allowed the small cuts at the die's edge to be transferred to the coin. Coop has a really nice graphic of a collar clashed die. If he doesn't reply to this post, you may want to ask him about it.

@cap, from the CCF glossary: Quote:
Broadstrike
Coin struck without a collar, thus when the coin is struck the metal is allowed to expand and increase in diameter. May be centered or uncentered, but must not have any missing lettering or design detail. "If you climb a good tree, you get a push."

Looks like there was a bad collar clash on a previous strike, possibly damaging the collar - then on this strike the collar didn't deploy properly, creating this broad strike. then as the coin spread out the collar clash expanded and stretched with the strike.
can you post up a pic of the slab to read the label.

As others have said, this is a broadstrike. The obverse shows collar clash on the obverse (hammer) die. While the reverse shows a similar pattern of peripheral, radial grooves, collar clash on the anvil die is quite rare. So it's more likely that these radial grooves are from grazing contact with the upper margin of the collar's working face.
