1972 LMC Doubled Die Obverse Help Needed

Between circulation damage, die polishing, coin condition it makes it hard to tell for sure what you have. The '9' tells me it is one if them, but as mentioned it is being hidden because what was there is now, not there.

You could, but the darkness of color would make matching die scratches even harder. It is not one of the common ones we see. You would have to check on later die state images, to look for possible markers.

Here's are the doubled dies that have counter clockwise doubling like yours does and my opinion and reasoning to why I believe it is or isn't the same die.

DDO-002- NOT A MATCH. The spread is stronger on DDO-002. It is clear when looking at the W of WE.
DDO-004- NOT A MATCH. Your coin doesn't have the rim Cuds to the left of LIBERTY and appears to be a later die state (thin letters in IGWT). The rim Cuds wouldn't disappear after they appear. Extremely rare DDO, but still check for die markers and see if you can get rid of the dirt in case it was the reason the letters looked thin.
DDO-005- NOT A MATCH. The spread is stronger on your coin. When looking at the U in trust on your coin and DDO-005 you can see the clear difference.
DDO-007- MOST LIKELY A MATCH. Everything I can see matches well, but I haven't seen any die markers to say 100%. It most likely is though.

Put it in a 2x2 since it is definitely a doubled die. You can try to get rid of the dirt with acetone or xylene.
