Thanks for the tag! Never seen one not on an error site. As long as it is incuse. It doesn’t look like it is, but could be the lighting.
If it is indeed a dropped letter, it definitely has value. As for how much? I don't know. I can't find any recently sold on ebay. @paddyman98 could perhaps give you a ballpark estimate.
Here is a sold example from Sullivan Numismatics for $150.00 https://sullivannumismatics.com/pro...8-d-hi-quarter-dropped-letter-t-obverse-ms-63
