Most of the last roll of wheats I searched were 52's. From what I have read 52's were invested in and saved in mass numbers. In circulated condition it is hard to find a 52 that hasn't seen its fair share of hard times. The key is to find them in an honest grade.
Could that hole near the ONE on the reverse, possibly be a strike through? Just asking. Not seeing extra metal pushed out, but then it has been in circulation a lot of years.
