Is there a thread where people can ask for price checks of physical crypto coins or a place that has the average prices listed? I'd like to see one as it'd make it easier for people to agree on a price. Most crypto coins don't have a large enough market to determine the exact value of them.
Agreed. There are so many times where someone has a coin on offer and I have no clue what to bid.
I've tried to get people to agree on a stable valuation for the different coins, but honestly it's not realistic. It's not right to control prices like that. It's all about what a buyer and a seller agree upon. Personally I believe a 2-3x valuation is appropriate for a loaded Casascius coin in mint condition. You're paying 1x for the face value of the coin and 1-2x for the numismatic value that is "Casascius".
There is some information you can use to help you understand what to bid, based on the size of the mintage (some coins have lower mint numbers and therefore are more rare). You also want to consider the condition of the coin.
This is the most concise source I've used: http://www.spotcoins.com/bitcoin/casascius
I think it's be appropriate so the seller isn't getting scammed out of their money and they have a ballpark estimate of what the coin is worth and they can use that base price as a guideline whether they want to pay higher or lower for it. It's really easy to just claim a price on a coin or collectible and someone will pay or sell at that price because they are misinformed of the actual item and the seller or buyer knows that and takes advantage of them.
