Dang, I'd like to see it out of the plastic. It looks like one of the nicer ones I've seen. I found a couple XF45 in NGC/ANACS plastic on ebay that sold for between $1300-$1800.
I can't help with the price but the COA with Walter Breen's signature interests me. and I wouldn't break it out without investigating that.
It looks like it's very nicely struck on a high quality planchet for the issue. The color looks a little light, but that could be the photo. The grade is EF. It's a 40 if you are old school and 45 if you are more modern. The source is First Coin Investors which was trying to regain its reputation at this point after, well, some less than the best practices with experts Breen and Taxy giving their approval. I don’t think that Taxy was with the company for very long so the packaging could be a rarity in and of itself.
"Mind your business!" Gotta love a coin that says that! I don't know how much they're selling for today but coins like that trend. That means, you really gotta be in the know, to know! Cool certification as well!
