An appraiser in the UK suggested that this coin has a potential value of 50 GBP, but I believe that it is possibly quite rare and has a higher potential value. I have not been able to find another coin like this.
This is known as a 'mule', where the obverse and reverse dies were not originally paired together but this is extremely common for the Conder token series.

Yes, I saw that on D&H, it states that the 16a with the plain edge is scarce but the 16 with the lettered edge has an RR rarity rating, which is second only to RRR. We are only showing the DH#10 on Numista, so please feel free to add this type to the catalogue. Alternatively, if you wish to provide here the weight and diameter, then I could create the listing for you and send a link

Thank you for your responses and useful information.
After I posted my question, I found identical tokens that were sold in 2016 (A.H. Baldwin & Sons), one plain edge and one lettered. The two sold together for 120 GBP.
I was not aware that "mules" were so common among these Conder tokens, so this is really useful information.
William Lutwyche (1754-1801) was the creator of this token and was active in token production from 1791-1801. It seems that he frequently created mules. According to the info on the Baldwin site, he "concocted numerous specious issues, and has been attributed with the manufacturing the bulk of evasions and lightweight coppers that appeared toward the end of the 18th century."
