Really nice canadian specimen sets, but I should of really put us int he title. @bear32211, I am looking for US specimen coins
Patterns are struck for various reasons by a government or their agent. Sometimes it is as a proof of concept: will the medal,designs, or dies be the right combination to provide viable minting requirements. A minting authority can choose to give some away to special dignitaries, or to the authorizing government office to make the decision to authorize the funds to go into actual production. I have attached a coin I found literally in a bag of several hundred Chinese coins from cash to early republic. It's a bronze pattern, or as NGC titled it, specimen. It did go to auction. Its a pattern/specimen of the famous design of the famous Sun Yat-sen silver dollar with the geese above the junk. Sorry about the quality of the photo, I had one day to see it in person after it was slabbed, to take an image, hug it and love it and call it "George" before express mailing it back to the auction house that sold it. I do collect Chinese cash coins as well as machine struck up to and including the Chinese Republic. I did a lot of due diligence on my own, and the auction house really worked hard. Only one was sold at auction in the previous ten years. It was fun to discover and pass onto another dedicated numismatist. Keep on hunting, you never know what you will discover in numismatics.
Okay, since no one else will ask or say it.... What purpose are you hoping to serve with the vast majority of this thread? There have been a couple very good and enlightening posts made, but they've been needlessly buried in what I can only assume you intended to be a list of such coins. As much as I respect and appreciate your efforts, you're accomplishing little by simply adding new ones in a fashion that makes absolutely no sense and forces the reader to have to wade through page after page of unpredictable posts that may or may not address what they're interested in or looking for. Take offense if you will, but if you'd like your project and effort to have meaning as well as be of real use to the reader, please consider taking the time to present your info in a more helpful and useful manner.
Here's another non-US specimen strike. PCGS SP65 RB. I could never hope to afford a US pattern/specimen, but this French piece was attractive, and while not exactly cheap, had a price in the low three-figures rather than four-figures.
An old and kind of stupid joke: Q: what do you call an Italian astronaut? A: a specimen. Didn't get It? Good. There's hope for you yet.
