I recently purchased this coin from an estate auction because I noticed in the pic that one of the beads appeared to be missing. Could not inspect it because of covid, so took a risk and bought it. I looked at it once home and saw that it is not missing a bead, but the bead is smaller than the rest and there are various sizes from the II to the front of the crown on obverse. Fairly new to coin collecting so I have not seen any like this. Is this a common thing with coins to have various sizes of beads in a row?
