But, We also need more info in order to better answer.
1- What is the SN, so we can approximate age; 2- we need pictures, to help establish condition; 3- is it just the revolver, or is there an original box, tools and paperwork included; 4- Are there a supply of cartridge cases with it, as nobody makes ammunition for the M53. All these things add or detract from value.

As an example, a 4-screw (early) M53 in ANIB condition is worth probably $2500, a 3-screw ANIB is about $1800, if you interpolate the 7 year-old values listed in the SCSW. Those values drop to about $800 and $650 for fair condition revolvers.
