Not to rub salt in the wound but I had my best $1 noodle ever today and found 13 alphabet coins with no doubles, I wonder if somebody decided to spend their collection. Mind you I still have never found a JC portrait of any denomination so it's all swings and roundabouts.
2016 50th Anniversary of Decimal Currency - I've seen this low mintage coin going for crazy prices on eBay lately.
2019 AUS - 'S' & 'U' x 2 - It continues to surprise me how often these show up considering they had a fairly low minage of 1.5m for each ... I guess not many people are putting them aside as you don't really notice the privy marks unless you're looking for them.
