A new auction that's pretty good
 

I found this autograph auction and it's pretty good for mostly modern items.They have all types of sports jerseys,photos and balls as well as a few celebrity and historical items.The auctions run 2 weeks and another auction starts immediately.
There's no buyer fees for the first year and every item has a COA from PSA,JSA,UDA,etc..
I had them sell a Tom Brady signed helmet with a UDA COA and it did pretty well and I got my money from them quickly.
I've also bought from them and that went smoothly too.
Here's a link to check it out if you're interested:
