1980s Mongoose BMX

[Botne539]

My grandparents found this old mongoose bmx in the garage, it used to belong to my mum when she was a kid. This was some time in the 80s and it says competition racing frame won winners choice on the side. Just wondering if anyone can tell me something about it or if it's worth anything. It wont let me upload a photo from my phone, keeps saying the file is too big. Thanks.
