There are five varieties associated with the Top Gun family.  Three varieties are quite common, and include 1822 1/A, 1823 1/A, and 1825 1/A.  However, 1824 2/B is the second-rarest variety with just 7 examples reported.  While 1825 6/F is the rarest, with just 5 examples now reported.  This variety was quite rare even in 1845 because this is the only Top Gun family variety which was not documented by Riddell in his 1845 Monograph!  
 
Overall, this is a top-level example even from the Top Gun family. I grade this as having VF+ details but this probably means it is more like EF/AU based on how this looked when it was minted. Most of the original silvering remaining in the fields. The reverse does have some pocket knife type light stab wounds, but in hand they are not too bad, and if this is being displayed obverse side up, they will never be seen!
