Your pic is great and your eyes are strong. I highly recommend picking up a copy of the Cherry Pickers Guide to Rare die varieties. It takes a lot of the guess work out, illustrates known examples and instead of randomly searching, you could for example better allocate your efforts. Then, you could for example search hundreds of a particular year on Ebay among others. Once you establish a search, save it so next time you can filter by recently listed first. That's how I did it, with my first search being the 1953 Proof Quarter with Re-engraved Tailfeathers. Within a few weeks, I spotted one raw for $60. I then had it graded and attributed by PCGS and sold it on Ebay for $3,549. I thought that was fun, so I went on to repeat the process several times. Then moved on to others as the book has hundreds of varieties. Best of luck with the Hunt.
