Hello. I got 3 ESPs I purchased second hand through time. It's an ESP SV STD, ESP Horizon NTB and a ESP M-II. What did these three originally cost and what would they be worth now?

look for completed ebay listings near your country to see what they resale for.

but off hand and at prices here in the USA I'd say depending on the condition they will be worth $1000-$1500 each on the used market

Deleted a bunch of off-topic posts and moved to correct forum.

briamor.bm, please make your own thread instead of hijacking someone else's. And since it was a further distraction - please make some effort to make your new thread readable and coherent. This isn't the place for stream of consciousness blogging.

To the original post: You can figure this out yourself with many tools available on Reverb, ebay, and other sites. Check completed listings and the Reverb pricing tool. Obviously the condition and specs of your specific instruments will need to be taken into account.
