I talked to Teletrade today and learned there are no listing or selling fees right now since January. Whatever the item sells for is what you get. They ask the items are at least $50 in value, but can be grouped into lots. This is quite a big difference from eBay and Heritage. There is a small amount of currency for sale with each auction, perhaps a couple dozen notes but each note seems to get quite a bit of attention and bids.
There are always fees whether direct or indirect. Teletrade also increased it's buyer's premiums to 17.5%. Buyers factor that into the purchase amount, and they just bid less than they would have before. A buyer that is willing to pay $1000 for a coin is now going to place a maximum bid which factors that in. Whether it's through sellers fees, or elevated buyer's premiums, TT is still making money from sellers.
Yeah, I might stand corrected, but I believe they now have the highest overall fees of any major auction house for coins and currency. I know some sellers who do high volume with TT and they've been negatively affected with the higher buyer's premiums.
Looking over their realized auction prices, I think one would do better with eBay, and that's not saying much. Might be less ground work, though.
