It’s a 1893 Philadelphia one. I’m still working on obtaining the 1893-S. I’m still working on one as it’s the last one I need to complete my collection. I have the money but no coin. One day soon.
The 1893-S dollar is not rare by any means. When I was dealer in Florida one dealer made a specialty of them. He had 14 certified pieces which ranged in grade from an “old ANACS” holder VG to Choice EF-45 in a PCGS or NGC holder. I forget which. The best one I had as a dealer was an NGC certified one in AU-58. I sold the same piece twice of around $20,000. You will find one, but do yourself a favor and buy only a certified example. There are diagnostics to spot real ones, but even if you know them, you need to have the certified to get all the money when you sell it.
They may not be "rare", but they are not cheap. Today a PCGS Gold Shield graded slab at G06 sold on the Flea for $4,150. This is why even though my passion is Morgan dollars I'll never own a complete set (unless I win Powerball). I'm not interested in owning a junk silver coin in a set no matter how rare it may be. I'd rather own multiple examples of fine coins with interesting strikes and VAMS all day long, all week long, and twice on Sunday.
When I need a coin like this, value wise, I stop buying and save my funds until I can afford it. So far that’s worked for me.
I'd have to stop buying for 10 years to touch a 1893S coin in AU condition. I'm just not doing it, period.
