Please be patient with me as I'm still learning and I do read how coins are made and about errors, but I also need to get opinions from people who know coins with one I have in front of me. That's how I learn and I took this up when my daughter passed away. So before calling me an idiot, explain why the coin is or isn't an error so I may learn. Then, you can call me an idiot Now I have a 69 & 70 lincoln cent off center, a kennedy half and a roosevelt dime with images on their obverse, and finally the 85 lincoln with a die crack? It's raised on the coin so is it a die crack or what else can cause this, extra material stuck in the die maybe? Look forward to seeing the replies on this one and thanks for your patience with me.
For the first two Lincolns they are probably not off center strikes. If the reverses are centered they are considered mis-aligned dies. This is very likely what they are as they are common. The Kenedy and Rosie look stained. The '85D Lincoln looks like a humongous gas bubble. If it is, it's one of the biggest I've ever seen.
Looks like glue on that 81 Kennedy half. Distortion appears to be clear, hence glue. Sorry it is a spender.
The 70 is centered on the reverse but the 69 is off the same amount as in the front. The area on the kennedy half has an edge to it an is raised a little, the one on the rosie is smooth and flat, does that make a difference? They all weigh out accurately as well. Finally, if it is a gas bubble that size, would it make it more collectable or are gas bubbles a dime a dozen, no pun intended? Thanks
69/70 are misaligned die strikes, a normal part of the minting process and not considered an error unless it's so far off that design elements are missing. An off center coin is off on BOTH sides and it must also have design elements missing to be collectible. Half and dime - Exposed to something during circulation, not errors.... just damage. 1985D - That's not a die crack, that's a gas bubble due to a poor plating job, common and not collectible.
