This is an electroplate mark of Mappin Brothers. The sun is their trademark and the following letters read “JM&B” for Joseph Mappin & Brothers".

Thx for that I have quite a few pieces with those hallmarks on them, I’m assuming electroplate is pretty worthless these days.

They may not be worthless. The site to which I always refer for electroplate marks (see here) tells me that Mappin Brothers only used JM&B up until 1852 with MB after that so your pieces certainly have some age and must date back to the early years of electroplating.
