1945 Lincoln Date Error

I am new to collecting and every little thing that catches my eye gets me excited. So when I came across this coin, you could have imagined how I thought I just found a rare coin. The 9 was a 2? How could this be? So, I found this forum and instead of posting right away, I found myself in a rabbit hole of interesting topics. Thank you everyone for creating a central place that I can learn and engage in this new, very exciting hobby that I love so much.
Can anyone explain this mint error or is this something that could have happened in circulation? What are your thoughts on this date error? Thanks again for the feedback in advance.
