Help with yatagans' inscriptions

[TVV]

Thank you very much Zifir, we are so lucky to have your help with these inscriptions. To the left of the maker's name, there is something that looks like a date, but I cannot make it out - does it make any sense to you? Reading the date may be important, because there was a Memis Agha who rose to prominence in the Trabzon and Surmene area in the end of the 18th century, early 19th century (when most of the yataghans with similar Foca silver hilts are usually dated based on similar examples).
