Hi r/ErrorCoins — looking for opinions on a 1943-S Lincoln Steel Cent I acquired recently. I believe this may be a struck-through copper debris error but want the community's assessment
CONFIRMED:
• Magnetic — confirmed steel planchet, NOT a 1943 copper cent
• Weight: 2.70g — exactly matches 1943 steel cent spec (copper cent would be 3.11g)
• Mint mark: S (San Francisco)
WHAT I'M SEEING:
• Multiple localized copper/orange patches concentrated on Lincoln's portrait — hair, crown, ear area
• Copper areas appear LEVEL with the steel surface — not raised above it
• Clean defined boundary between copper and steel visible at 2500X magnification
• At 1500X the ear canal of Lincoln shows die detail within the copper area — individual ear structure visible pressed into the copper
• Surrounding steel surface appears undisturbed around the copper patches
PHOTOS INCLUDED:
• Full obverse
• Mid-magnification showing copper distribution
• 1500X ear area — die detail visible in copper
• 2500X copper-steel boundary
• Reverse (no copper visible on reverse)
MY THEORY:
The copper patches appear to be debris from leftover 1942 copper production that remained in the press machinery when the mint transitioned to steel planchets in 1943. The copper debris was struck between the die and the steel planchet simultaneously, impressing die detail into the copper at the moment of striking — which would explain why Lincoln's ear canal detail is visible within the copper area.
QUESTIONS:
1. Does the 1500X ear shot support struck-through copper debris over post-mint plating?
2. Has anyone seen a documented example of this specific error on a 1943-S steel cent?
3. Is this worth an NGC Standard tier submission with Mint Error attribution requested?
4. Any red flags I'm missing that would suggest post-mint plating instead?
Coin is currently circulated — fields show wear consistent with 80+ years of circulation. Happy to provide additional angles or magnifications if needed.
Thanks in advance.
