I always assumed (maybe even correctly) that they were rushed into production without testing the metal mix — and that incomplete metal mixes led to many peeling laminations. The coin maybe heating and cooling with the weather could have caused the incompletely-mixed metals to expand and contract at different rates, causing the separations and peeling.
What seems to me like a high number of grease-filled dies with missing letters and design elements (such as the two shown here) might have been the result of the new metal mix sticking to dies and needing more grease than other alloys needed.
This is all guesswork on my part. I don't actually know why these nickels seem to have so many problems. But I'm glad to have so many interesting anomalies available on these nickels.
I bought all of the ones pictured here on my last two trips to the coin shop. About $1.30 per nickel. Fun and affordable.
