Coin Show Price Guide

I keep most of the current prices in my want list.

I can access my want list (PDF), NumisMedia, and ebay from my Android phone.

Price lists on apps should help to get rid of some of the rip offs at shows.
If both the dealer and buyer consult their app for the current price, a deal where both are satisfied with can be more easily negotiated. May take a little more time per deal.

It is really a bit like TPP. (Third Party Pricing)

Wouldn't go down well in a bazaar in the Middle East.

I do the same as Buddy......Shop for less then 5 coins so I can lock in my searching.

I go to coin shows all the time and over the years I've found that regardless of having any price list with you, it really doesn't matter. If a dealer says he wants $10 for a coin, yes you can haggle him down. But to say in my price list it is only $5, usually the dealer will say just find someone with that coin for that price. If you want to waste time arguing about what his prices are compared to any price guide, you'll usually loose.
Showing any price list to almost any dealer is basically useless. Yes it does allow you to know what a coin may, should, could, might be worth but if you can't get it for that price, just a useless price list. All such guides are just that, GUIDES. I've found over the years that the best thing is to know what I think a coin is worth to me. I also walk around comparing prices on any coins I'm interested in. I've made many lists for what I think I'll look for and usually always leave that list at home.
I'm not knocking price guides to take to a coin show, I just have never found one to be of any use.

@just carl, Great advice. From my 20+ years of experience, dealers at coin shows seem to resist haggling by making a price guide reference.

However, a twist on this logic is finding a dealer that has multiple items you want and buying in bulk.

Show a dealer $50 and they will scoff at haggling.

Show a dealer $1,000 and you have their full attention.
