Reluctantly, Tiras, I will step out onto this thin ice and answer your questions because you appear to be rather nieve about guns and ammo. If I am wrong, no harm intended. I also hope you are at least 18+ yrs old and better 21 because if you aren't you are messing with illegal stuff.
New, factory loaded ammunition similar to what you have sells for around $25 per box of 50 and your ammo should certainly be worth that. I would say yours is worth $20-$30 per box. If you wanted to sell quickly, price it under $25 and if you want to max out, go for the $30 but it will probably move slower. When selling this to someone that will require it to be shipped to them, you need to consider the shipping cost because they will. Shipping for ammunition must be by Fedx, UPS or the like because it is illegal to mail ammo and it is very heavy so the cost is high. Collectors, ammo and military, may have enough interest to pay more for single boxes but I think your best market, for selling quickly, is to shooters.
Many people look at the reloadability of brass when they buy ammo and yours is reloadable but requires a little extra effort and tools to remove the crimped-in primers and then remove the crimp burr. But the brass is generally thicker and longer lasting so some folks like it.
Your ammo is made to military specifications (MilSpec) of the time. It has a 230gr Full Metal Jacket (FMJ) bullet and I believe it has a speed of about 750fps mv. This type of ammo is commonly used by private folks for practice and some target games but many feel it is not effective for personal defense. The cemeteries of Europe and Asia are full of people who might argue that point.
Good luck. If you decide to sell it, PM me and I'd be interested in a box or 2.
