Cool pickup, Johnathan. Given all the surface contamination present, I'd suggest using Coin Care or acetone on a swab to gently lift and remove same. Otherwise, the verdigris will eat into the token's surface. IMHO, it's worth conserving.
Early Philadelphia City directories are readily available at this website:

While residents are listed alphabetically, they are also listed by occupation or business toward the back of each volume. We know that your H.T. was a druggist, chemist or apothecary, so you might look under those headings to see if you can match the initials. Since your token is likely mid-century or later, you might work your way backwards, from the latest date.
