We have two ways to cover guns/accessories 1) scheduled 2) unscheduled.
The rate and coverage is the same for both ways. Guns over $10k have to be scheduled.
The difference between the two is the valuation come claim time. Scheduled guns are valued at stated amount and receive up to 25% of the stated amount if it is insufficient to replace.
Valuation under the blanket/unscheduled is fair market value which turns out to be the cost to replace new cost for any gun still in production. For guns out of production we use a combination of close to 100% blue book, current listings (gunsinternational, gunbroker), current/past auction sales of similar items in the same or above condition. For the majority of claims, especially theft, we don't know the condition prior to claim however our partner, Hanover, has exceeded my expectations.
Unscheduled accessories (i.e. optics, suppressors) are on actual cash value however we give 24 months to replace in which case the difference of actual cash value and replacement cost is paid.
I only schedule my guns over $10k in value and use a blanket/unscheduled limit on the remainder.
