I was thinking I saw them somewhere for upwards of $100.
You probably did. That happens. It's usually for a dime that had an extremely low mintage number or for some of the last years of Carson City minted coins.
ETA: For example, you can commonly buy an 1892 O silver dollar for under $40, but it's almost impossible to win an eBay auction for an 1893
O dollar for less than $150 simply because of the limited number of 1893 O dollars minted.
There were over 2.7 million 1892 O dollar coins minted but only 300,000 1893 O dollars minted.
And you have to remember when you see an 1850's era U.S. silver coin with the arrows on either side of the date, it means that coin was minted with a lower silver content (70% rather than 90%, I think
) when the price of silver skyrocketed in the 1850's so the silver content was reduced to keep their melt value in line with their face value. If you see an 1850's silver coin without the arrows, that coin has the full 90% silver content and will sell for a higher price than a comparable coin with the arrows.
