Dear Jose,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a WW1 German bayonet with an so-called butcher blade because of the thickening of the tip of the blade. The bayonet comes with a metal scabbard.
This piece is in bad condition and there are serious corrosion damages visible in the images provided.
A fair market estimation would be between 60 to 140 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.

With kind regards,
Georg
