Thank you for contacting Mearto with your appraisal inquiry and the additional photos.

It is a beautiful handbag. 

However after having examined the photos very carefully we have come to the conclusion that it is not an original Gucci handbag.
The a leather tag on the inside of the handbag should have been stamped or embossed with the Gucci name and not attached with a golden label. We have examined the canvas, the leather trimmings and the stitches on the photos and again the quality is not quite the usual high Gucci quality of leatherworks and stitches.
These high-end expensive designer brands have been copied worldwide and in particular in the 1960s-1970s and 1980s there were sold many very good copies of the expensive brands however they tend to show lack of quality and finish after having been used.

The sentimental value it represents to you will be much higher than the market value.
I am very sorry for the unfortunate news. 
Please let me know if you have any additional questions. I’m happy to help. 
Thank you
