Is this a Chester assay mark? If so the “P” is 1898. Incidentally you could have added this to your other post by using the Reply button.

Sorry im new to this. Yes it is a chester hallmark, the image was just too large to upload. Do you know any valuations for my pocket watches, fully working good condition. Thanks for the replies

Check out eBay completed auctions for possible values. It’s a very good indication of what people are prepared to pay rather than what an “expert” might want you to hear.
