Dear Patrick,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a Daab or Darb sword how it is common in Thailand. This type of a single-edged blade sword is also used in the neighbour counties but the decor and the depictions on the blade localise this piece in Thailand. The details of the decor and the blade are a hint that this piece was made in the 20th century for decorative purposes and not for the usage.
The question if the scabbard was made out of silver is not to decide on the base of images. The corrosion is more a hint that it was made out of a white metal alloy or is silver plated. At the end of the scabbard I see a yellowish metal coming through the silver. This needs o to be tested physically.
This piece is in good condition and there are no serious damages visible.
An estimation would be between 80 to 150 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With kind regards,
Georg
