Triple minting error on 2009 P Professional Life reverse

[RollMeUpAbe]

After searching 4 rolls of 2009 P PL Lincolns I found a lot of minting errors but no varieties that I can match to the pictures on Wexler's site. The coin pictured looks like it has a die crack on the T, a die crack in the windows on the far right of the building and something struck thru in the center of the building. I am thinking it may be metal from the die crack on the far side of the building. Something else I found interesting is examples where a coin has the die crack in the windows but not on the T.

What would cause the die crack on the T to appear on some, but not others? One explanation could be the timing of when the die cracks first began but it seems odd the T would have no sign of issues and then have a large die crack.

The roll of coins you searched isn't from one press. The coins all feed into a bin from many different presses.
It can't be metal from the crack

[MintErrors]

Typically there are between 9 and 15 minting presses operating at the same time. As for dies which make coins, they typically strike 600,000 to a million cents before they are retired. Since they do billions of cents, they make a lot of working dies per year. Once coins are minted, all those coins go down to coin counting machines and typically these bags are now huge. The mint has some rolled, but majority are rolled by third party companies like Wells Fargo, Brinks or other companies.

Most die cracks are pretty common. IF some one really wanted one, they may pay enough for a fancy coffee, but that is stretching it. The more dramatic and rare the error, the more it is worth.
