1883-S Morgan. It takes a heck of a lot of wear to wear the rims off a Morgan, but the reverse rim is completely gone. If it hadn't gone through a slot machine about a mill ion times it would be worth something.
Since you won't be able to tell, here is an 1805 dime, a 1798 dollar and what I think is a George VI half crown
My lightly circulated 1916 Mercury dime. It's so worn, there's been debate if there is a "D" or not. You judge for yourself.
I have a huge lowball collection! I find them a lot of fun especially when the wear is smooth, even and tasteful looking or selectively worn in given areas but less so in other areas. The lowballs I really don't care for are ones that have ugly stains. For example I had the unique PCGS 1875-CC 20 Cent piece in PO01, however I didn't like the look of this coin and someone agreed to buy it off of me for profit so I sold it. My only coin I have left graded Poor-1 is a 1921 Peace Dollar by SEGS. I have loads of Fair Condition lowballs I enjoy a lot. Sometimes coins in Poor condition are too overkill worn in my opinion. Fair condition ones I find the most attractive for lowballs. In the lowball business, people pay the biggest money for solid, non-details graded Poor-1 specimens. Poor-1 is the equivalent of MS70 to the lowball collector.
Wow!!!! WOW, that's got to be the most beautifully toned lowball I've ever seen. I can't believe it actually graded solidly by PCGS given the wear. I think you have an unique set of circumstances with this one. Where did you come upon this coin? Were you the original submitter and did you think it would grade as it did?
Thanks for your comments. I bought that 1928-D SLQ as a raw coin on eBay back in October 2014. It was Buy-It-Now for $21.50. I thought it had a great shot at grading with PCGS due to the toning pattern, so I tried submitting it to PCGS for grading and TrueView photo -- and it graded as problem-free first time through. This is what the seller had in his original ad: "This coin comes from a silver collection that has been in storage for the past 40 years. I make no claim as to the grade of the coin, so please examine the photos."
Very nice early survivor Mainebill! My suggestion is to polish the Slab if you can to remove those scratches as they detract from the appearance of that evenly-worn coin.
