And rightly so, @CoinCorgi. That is a nice example in spite of the alleged cleaning - which to me at least is not evident. I mentioned my first example - in a slab graded VG10. Here it is. If I find a better one I may upgrade this.
Thank you very much for your comments @drbrummer. I had not realised full strikes on '49-O's are so scarce, so it seems I got lucky with this one. Beginners luck, I guess. I did check for reverse die alignment, but it lines up straight with the obverse when the coin is flipped, so it does not have a rotated reverse. I need to learn more about this issue, die varieties and striking characteristics. Thank you again for your comments!
