I was wondering, can you just take your violin to a violin shop and ask them to value it, without real reason other than i was wondering how much it's worth?

Cause i was intending on buying a new violin next year, about £2000, seeing as the one i have now only cost me £500, however i'm beginning to think it's worth much more. Since i bought it the sound has really opened up and i love it - it sounds great, and i just got back from string orchestra and everyone was playing my violin and they were amazed at how great it sounded (and how nice it looked

) despite the fact that they all had violins that cost thousands (they didnt know mine was only £500!). I know the luthier lowered the price of it for mwe but i don;'t know by how much.
I don't even feel like i want a new one anymore as i love this one even though im always like 'how can it be great.... it was £500!' I know with violins it's more about how the violin works with you than how much it cost etc. but still

For now i don't want a differnet violin so i think i'll keep my money and save even more, then get a better violin when i actually need one

But would i be able to get this one valued or would it be a waste of time?
(Btw the reasons i'd beenintending on buying a new one are.... 1) as a present off my grandparents for my 18th birthday - they want me to get something i'll keep and use etc., 2) for music college/uni when i go... surely a £500 violin isnt good enough for that? and 3) when i went to try out shoulder rests i got given such a nice violin to try them out on... i totally loved it and it made me wonder if i could do with a better one myself
