Best thing is to educate yourself on the configuration of the Model 53 by looking at websites such as
Gunsinternational or books such as The Winchester Book by George Madis. According to Madis, the "standard" Model 53 (there were several special order options) has a straight grip, shotgun style butt, 22" round barrel with ramp type front sight and six shot magazine. It came solid frame or takedown. I would give extra scrutiny to any variation to that configuration.
The one thing I would look for is an older 1892 rebuilt with a 53 barrel and magazine. The "Model 53" designation will be stamped on the barrel and if the upper tang is marked "Model 1892" or "92", it is most likely a put together gun. I've seen several older 1892s rebuilt with model 53 or model 65 front ends and advertised as such. Other than that, as the others said, condition and originality have a huge impact on value.
