Greatly depends on condition and variation, from a 200 well worn shooter to a rare mint condition smoothbore for 2,000 or more. For a excellent condition 12-A (round barrel) standard variation 500.00 12-C with hexagon barrels bring more, as do certain sites, and of course there's 3 levels of engraved and a 12-F (highest engraved) can reach 10K.
The best was to determine the current value is to look for a like model/condition SOLD on gunbroker, gunsamerica, gunsinternational (all .com).
Remington didn't make a Model 12-2 but Model 12-A-F & and CS. But the value is GREATLY dependent on condition without that it's anywhere from a 200-1,200 gun NIB.

Well there is no Remington Model 12 shotgun, a model 12 is a 22 lr, they did make a smoothbore but it would have said so. A smoothbore model 12 is rare and valuable but I doubt that's what you have if it doesn't say smoothbore it's probably shot out.
