I recently obtained a 1935 $1 Silver Certificate signed by Mel Ott. I am thinking of getting this certified, as if it is real, it would be quite a find. The sig looks good against the exemplars I have found online, but I am not an expert on his lines and his signature seems a bit on the easy side to forge if it was practiced. What does anyone think on this? Should I fork the $100 for PSA/DNA?
