I only have a few without coupons right now. They can be seen here

Rhett probably has a fair amount more and he is highly recommended!!
Other than that there are large groups of low grade ones at auction sometimes. That will be a good way to get a bit of momentum. It just takes a bit of time to find them. I am not aware of any groups at this moment but there will be in the future. Good luck.
