My old Silverberry that I acquired a few months ago leaves are looking a bit yellowish, scratched the branches and everything is still green. Is this normal or something I should be concern? Thanks in advance!

Plants can get a golden hue from cold exposure, it's a healthy response most of the times. I don't know this species so I don't know if it should.

Ficus does it too, but that means it's dead. Junipers do it too, in their case it's normal. A winter hardy plant species showing this hue is not an issue. If a non hardy plant does it, it's a bad sign.
Keep in mind though that things can stay green in the fridge for a long time and that a bark scratch is not the best test in this case; it shows cold preservation instead of livelihood.
 
Gumis are semi-evergreen, varying between species and severity of winter cold. Do you know the specific species? Was it outside this winter? Mine would hold many of it's leaves through winter in GA but lost almost all of them by Thanksgiving this past fall here in MI
