Okay - Last Question, I promise! These 4 look strange to me. I'll post more pictures if you guys need them. 1981 P - This one looks like "Liberty" is set higher than it ought to be & 1981 looks lower. 1984 P - The "I" in "IN" is gone. Has that just rubbed off over time, or an error? 1991 P - I think the images from either side may be making imprints. 1999 P - Is this toning? Also, did they change the size of font for "IN GOD WE TRUST" from the 1980's to the 1990's? The 1991 coin looks significantly different from the other two. Sent from my iPhone using Tapatalk
1981 - This looks like circulation damage. 1984 - Grease-filled die.....very common and not worth a premium. 1991 - Looks like dirt to me, but if someone stared long and hard enough, there is no telling what they might see. 1999 - It looks like ordinary discoloration from circulation. Even if it were toning, it is not the kind that would add to the value. Chris
