Not silver - this is a very Rare, solid 9ct Gold Stamp Holder shaped as an Envelope. I believe the hallmarks are for Chester, 1918. The envelope appears to be rose gold gilt - you can see the variance in colour in the photos.
Included is the stamp which came with this. Please see the photos for more detail and information re: condition and do feel free to ask any questions.
