USA shifts

Just wondering if shifts such as




are anything other than just an interesting item?

This may be a specialty area requiring someone with a lot of experience to judge its value/marketability.
Some stamps are hard to find with perf shifts, while others are commonly found shifted, so it depends a lot on the particular stamp in question as to how common the shift is.
Unscrupulous dealers have been known to sell them for very high prices as rarities to newbies, possibly giving them a bad rep.
My truly wild guess is that they are quite collectible and would fetch a few bucks extra on ebay, etc. whenever the perfs go substantially into the neighboring stamp.
Inspektor has shown some perf oddities on his Downey stamps.

Greetings Mr. guyana
.
Perforation shifts does not even have a section in the "2001 Catalogue of Errors on U.S. Postage Stamps." Misplaced perforations (or Misperfs) fall into the category of EFO (errors, freaks and oddities). Mr. Butterflies is correct in his assessment.
.
The good news is that misperfs of commemorative stamps are more scarcer, thus more collectible, thus more valuable, than regular issues and coils. The bad news, the Preserving Wet Lands commemorative is not a popular topical, say as First Man on the Moon because of the aerospace being a much more popular topic. The good news is your misperf has eye appeal. The bad news is that the misperf is not overly dramatic and does not change the design (that is, the denomination and birds are intact). Misperfs that effect a third or more of the stamp claim a high premium.
.
Overall, I'd say that it is a keeper.

Misperfs are worth whatever a collector of misperfs is willing to pay. You see these listed in auction catalogs fairly often. They are definitely collectible and oddities.
