It would be remiss of me to not comment in this thread ... I am a dedicated lowball collector and thoroughly enjoy pursuing and promoting this under-appreciated aspect of the hobby.
If you forgive my soapbox for just a moment ... the following must be said ...
There is a significant numismatic difference between a well worn coin and a collectable lowball coin.
I am in pursuit of collectable lowballs across four USA series ... and in my judgment the standard is coins certifiable by a TPG
as PO01 ... the ultimate lowball grade.
To qualify as a collectable lowball ... not a simply well worn coin ... the coin needs to meet each of the following requirements:
1. Must be positively identifiable by type.
2. Must be positively identifiable by date and mint mark. Exceptions occur here for single year type coin such as the 1921 Peace dollar
which can be identified by experts without the date visible.
3. The coin must have honest, original surfaces without prior cleaning.
4. The coin must be undamaged, i.e., no graffiti, significant rim hits, scratches, etc.
5. The coin must be worn to PO01 state ... and not lower!
All that said ... I currently have 27 PCGS certified PO01 coins ... honest lowballs.
I won't bore you with all of them.
One example from each of my four series of interest:1918-S Walking Liberty half dollar - PCGS PO01
This is the only PO01 Walker ever certified by PCGS. Look up the population report ... the only one in over 370,000 certified Walkers. 1893 Columbian Exposition Half Dollar - PCGS PO01
We had great fun here at the CCF discussing the date on this coin ... jbuck remembers contributing to that.1921 Peace dollar - PCGS PO01
Refer to my comments above about single year type coins. I currently have 9 Peace dollars
as PO01 ... a diabolically difficult set to assemble.1893-S Barber half dollar - PCGS PO01
Key date ... Pop 1/0. I have 15 of the 22 total PCGS certified PO01 Barber halves
Whatever your lowball interest is ... I certainly encourage more folks to embrace this still sidebar aspect of the hobby.
Hopeful to see many more well worn coins in this thread ... they do not by any means need to be certified PO01 .... simply show us the lowest that you have and are proud of.
