Dear Paul,

Thank you for contacting Mearto with your appraisal inquiry and for your patience. Considering these images, this is:

A beautiful set of 5 vintage swords including katana, knifes and type IIb medieval-in-style European swords. Overall this remarkable set represent an heterogeneous collection that could be very sought after for antique swords collectors. According to the styles and images, without physical inspection, they appear to be made in the 20th century. Such weapons became very popular for Western collectors since late 19th century. Hand-carved and hand-painted, good condition with signals of age.

A fair market estimation would be between 500 to 800 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.
