I collect errors but I won’t take a guess at the value. It is definitely a beauty and that is a rather large cud. Congratulations.
I've purchased similar Cuds for $25.00 - $40.00 A bit more for attributed Cuds. On eBay they list them for hundreds and even thousands of dollars. It's just a worn die issue. They look neat but they shouldn't have such high premiums.
