Where can I buy real/legit NFL patches for jerseys?

Not sure if this topic is posted elsewhere but I didn't see it. If so, forgive me, but this is a question I've had for a while.

I have experience collecting NHL jerseys and I know there are companies that produce legit patches (National Emblem produces legit patches and they can be found on different sites, such as sportsk.com and even eBay). So I was wondering where I can buy legit NFL patches to put on my Nike jerseys. Does the NFL allow for such patches to be released to the public like the NHL does? If so, how might I obtain them? I see some on eBay but I'm aware, just like with jerseys, there are an overwhelming amount of fake patches around, or those that are custom-made and many of the ones on eBay look fake to me from first glance. I'm not interested in buying any fake or custom-made patches at all. I'm looking for official, legit patches to buy for my jerseys, such as anniversary ones and tribute ones. For example, I'm trying to get a hold of the following:

Super Bowl XLVII patch
Super Bowl XLVIII patch (I ordered an Eric Decker Broncos Super Bowl jersey off of NFL Shop months ago and it came with a metallic sort of Super Bowl patch on it, so these have to be sold separately somewhere, no?)
Baltimore Ravens Art Modell patch
Tennessee Titans 15th Anniversary patch
Houston Texans 10th Anniversary patch (My friend is a big Texans fan and went to a game in 2012 and said he was pretty sure they sold them at the stadium, so these have to be out there still too.)
Indianapolis Colts 30th Anniversary patch

Are any of these patches officially-licensed and released to the public? Does anyone know where I can buy them if they are?

Lastly, to be sure, I've heard NFL captain patches haven't ever been released to the public. Is this true? From what I've heard, the NFL hasn't allowed captain patches to be accessed by the public and that they are commonly faked or made by unlicensed sellers. However, there are no official ones produced other than the ones on gamers. Just wanted to confirm this.

Thanks!

Willabee and Ward used to make Super Bowl patches, so any by them are genuine. The current Suoerbowl patches are heat pressed on, so not an embroidered patch. You cannot get hold of them I'm led to believe. As for the anniversary patches, some were produced for the public to buy, but they were limited to the anniversary season so will be hard to find.

The captains badges were not released to the public so the only ones available are not official.

It seems as though Nike has decided to release "special event" jerseys in limited quantities in the Game style which come with the actual patch for the Super Bowl and some team anniversaries. I've seen these on NFLShop, official online stores of the teams, and nike.com.

I've managed to get a hold of a 2013 Broncos Super Bowl patch jersey (I believe Nike released these in Manning, D. Thomas, Decker, Welker, and J. Thomas from the ones I can remember), a 2014 Seahawks Super Bowl patch jersey (I've seen Wilson, Lynch, Sherman, Chancellor, Baldwin, Thomas III, and possibly Wagner), a 2014 Patriots Super Bowl patch jersey (I've seen Brady, Edelman, Wilfork, Revis, and Gronkowski), a 2014 Jaguars 20th season patch jersey (only available in Bortles from what I've seen), a 2014 Giants 90th season patch jersey (only available in Manning from what I've seen), a 2014 Steelers 40th anniversary of Super Bowl IX patch jersey (available in Polamalu and in very very limited quantities Bell, as far as I know) and I just ordered both the new 2015 Dolphins 50th season patch jersey (available in Tannehill and Suh) and 2015 Ravens 20th season patch jersey (available in Flacco, Mosley, Suggs, Forsett, Smith Sr., and Tucker).

I'm missing some like the Ravens and 49ers Super Bowl patches (2012), Texans 10th Anniversary patch (2012), Titans 15th Anniversary patch (2013), Colts 30th Anniversary patch (2013), Panthers 20th Anniversary patch (2014), as well as the patches for the late owners of the Ravens (Modell), Lions (Ford), Bills (Wilson), Titans (Adams), and Buccaneers (Glazer). I know the Bills offered very, very limited quantities of customized Game jerseys with the RCW patch on the Bills' online store that I'm sad to say I didn't order in time. Besides for that, I know Nike did release the 2012 Super Bowl jerseys. Does anyone know about any of the other ones I listed? Did Nike release any of them and I missed them? Or did the teams release the jerseys or issue patches I don't know about? I can't recall any of these being officially available. I'd love to have them all, including the patches for the owners, but if Nike didn't release them and the only options are fake fan-made patches sold on eBay, I'll easily pass. Not interested in those.
