'93 Lincoln Multiple Errors Or Just Greasy Die

I bought this coin from a fellow who chastised the Mint for allowing errors in 3 unrelated stages of its manufacture.

First, he said, "[T]he planchet displays a custard effect throughout its surfaces on both sides, which is the result of poorly manufactured blanking strips."

Second, he said, "[T]he reverse die clashed with an obverse die as may be seen by the outline of Lincoln's beard within the Memorial. He said the tool room should have replaced the reverse die when it replaced the similarly damaged obverse die, but failed to do so."

(How'd he know they replaced the obverse die?)

Third, he said, "[T]he coin was struck more than once, in collar. "This," he said, "was caused by a malfunction at the coining press."

His final comment was this: "Given the precautions the mint keeps in place to eliminate minting errors, the production of a single coin exhibiting 3 unrelated errors seems beyond belief." "This," he said, "makes it a rare coin indeed."

I listed the coin on ebay and used his description. Another ebay member sent me an email and told me the coin was simply a "grease filled die." He said he had a coin that looked just like mine and that he was told it was a Grease Filled Die. He said "It looks like the anvil/reverse die and the hammer/obverse die had grease in them."

I would greatly appreciate it if you could please give me your opinion on the above. If I have the coin listed with incorrect information, I need to pull it immediately and correct the problem. THANK YOU!
