If you look around at the various websites run by militaria experts you can get an idea of what your items are worth. You can also use Ebay's Militaria section to help get an idea of value.
You can also use the internet to find manuals/help guides on properly identifying whether you items are genuine or forgeries.
I buy a lot of my WW2 miliaria off of eBay.com. The main reason is that i can shop around and keep looking until I find the item that interests me. This site will give you a good idea of the value of militaria. However, some items are inflated due to the frenzy of the bid war. On the other hand, some items are sold below their value because the Seller doesn't know what he has and/or does not describe it well with photos or info.
IF you watch it over time, you will learn to understand what the value of an item really is. There are many people who use this site so they will pay the going price in most cases. Even if it is inflated, then that is better for you if you plan to sell your items. Post yours on eBay as soon as their items closes and the "losers" will come jump on yours.
Also, note that items grouped together that are related will bring a much higher value. If you have several medals from a Veteran, then sell the items as a group along with a photo of him or his papers. The grouping will be worth more than the individual item.
For example: You may have nice uniform with patches and ribbons and say this belonged to a specific Vet. But so many people are selling such uniforms that they pieced together from "spare parts". If you have his name in the coat that would be more proof it is from a veteran. If you have a letter from the Vet, then that will be even greater documentation and raise the value of the coat.
Warning: Be sure you describe your item EXACTLY. If you mislead someone, they will want their money back. For example, you may have a small pin that looks like one you see on eBay. But one may be marked "Sterling" and that could double the value. If you know know anything about it, just take photos and describe its size and especially its condition.
You do not have to use eBay to sell it. Just browse it and see what the items sell for.
