Residential & Commercial Security - Locks, Keys & Dead Bolts - need to get into vintage safe

My wife and I have inherited her uncles old house that contains a old Victor safe vintage 1930-1940s from a old drug store.
Her uncle stored a lot of morgan silver dollars in it and other stuff that we do not know about.This thing weighs in at over a thousand pounds.
It has a combination lock and a big handle we have the combo but we can not get the sequence right as you have to turn past the first number 5 times and then go the other way past the number 4 times etc.
Will I have to call a special type locksmith to get into it? I do not want to destroy the safe but I need to get in there. what might be the cost of having a safe cracker come out and open it?

A 4 number combination usually indicates 5 wheels in the lock. Hence why you need to dial it 5,4,3,2...etc.

Always start with the dial lined up to ZERO.

Turn the dial 5 times clockwise lining up the first number on the index (mark).......turn the dial counter-clockwise to the second number 4 times....etc...etc...

when you have dialled the fourth number counter-clockwise twice, stopping on the fourth number...spin the dial clockwise until it stops turning.....the lock will be open.

Thanks for the quick response we will give it another try this weekend and let you know.I have printed the directions.

When you stop on each #--give the door a whack w/ the side of your hand..............
