1999 D LMC Looks Odd- See L In Liberty And Back Of Neck/Hairline

If looks like the 'L' is suffering form split plating on that device. This happens often on the devices near the rim. We often see it on the reverse devices. The neck area looks like something stained the coin there. Most stains remain with the coin the rest of the coins life. Some remove them, but risk getting a 'genuine' grade when they get it slabbed. Best to leave them alone on the plated coins for varieties. If I use mineral oil to remove the crud around the devices, you have to do this carefully to keep from scratching the coin. Sometimes the gunk will contain sand and it will scratch a coin when you are removing it. So it is best to know how to avoid damaging a coin, or just leave it alone. If done wrong, it will ruin the coin for other collectors.

I see in that area some die abrasion that affected the hair, the shoulder below the collar, the 'TY' is also a little smaller. That looks like a case where they tried to remove clash marks in that area. The field being reduced would affect the strength of those devices in that area. (thanks for your added information on what you saw) Now I can see what happened in that area. Even though there is no premium for this, it is always nice to know what caused it.
