NEED TO KNOW VALUE CANT FIND GUN ANYWHERE

I have a beretta 85 cheetah 380 nickel and wood. Was told only made one year. Want to know the value new in box never been shot with all paper work? Told it was made in 1990.

value for your cheetah would be around 400 in box,,the cheetah series was made in about a half dozen variations and include models 84 ,84bb,85,,86,,87,,and a 87 target model and an 89 gold standard model ,,,the 85 F was only made in 1990 but it was patterened after the 92F gov model and came in matt black,,the nickel and wood finish was discontinued in 1991,,
