Sure! Plus grades are kind of newfangled. They leave a lot of room for interpretation. (This is why it's important to hone your skill as a grader, so you can decide if this is a 64.2 or a 64.6 or a 64.9.) On this coin, it's not so important, but on an '84 S the difference is many thousands of dollars. As such, this is a wonderful piece to learn from! Congratulations, and glad you got back into things!
