Value of L C 7,62mm blanks

I have two ammo metal boxes with 200 rounds of 7,62mm NATO blacks in
M13 links in each box. these are marked 200 CARTRIDGES 7,62MM NATO
BLANK XM82

What kind of price would be fair to ask for gun show this weekend ?


Thanks RS

if it helps, I sold 240 rounds (boxed 20 per box) not too long ago online for $35
not linked,

Also noticed the ammo cans for 200 rds of blank 7,62 LC Nato are selling for $30 in exc cond too,
without the blanks

Thanks for the price
