Need to know which model.
50-250
100-300 or so
Not enough info to answer. What model, blue or stainless, what barrel?
100-450 or so
value depends on overall condition
550 dollars for new one.
100-400 USD or so
There are several handguns made by Taurus with a PT designation... you would have to specify specifically which one (PT92, PT99, PT101, etc.). General rule of thumb.. for a firearm in good condition, used, you shouldn't expect more than 10% depreciation from the price of a new one.
Can't be answered without knowing what model.
