Inherited banjo and fiddle(violin)

I inherited two instruments years ago and was wondering if they have any value other than the memories of weekend picking in our back yard or at my Uncle's house. Those are priceless!!!

I have looked on the internet but have discovered nothing about either one.

Uncle's fiddle:

has markings inside: Made in the peoples republic of China
and there is a stamp/marking I believe has the following letters HSINGHAF
and a set of numbers

Grandfathers banjo:
four string with a skin drum with 39 clips/screw attachments
on the top of the handle of the banjo it looks to have some type of stamp or mark really can not
make it out, may be a spade symbol
the four string holder knobs have pat.may,8,88
there is another knob down about 8 inches from the top that the knob say USA patent pend. Grover
My grandfather was born in 1895 and passed away 1996 he had stated that this was a used
banjo when he got it so I know the 88 is (1888) he had had it since approximately 1901-1903 he got it
as a child from his father who was born 1865

If photos are needed I can post

Any help or suggest of where to look is greatly appreciated
