1955, 1957, 1958 P Mint Set Sealed

You should start by trying post some photos here first, because grading is rather $$$ costly,
If you don't know exactly what you have. I realize that opening your mint sets is another thing
to consider, whether to do or not.

I would not advise sending in these coins no matter how good they look. 99% chance you won't come out ahead

Zinkin - I'll give you a bit of time to post up images before this topic will get locked for lack of them
But for posting images, 300K is the max allowable file size - yes that is sufficient size for great pictures to be posted.
No images on your scope of computer monitor - we want the actual image file.
Generally 800 pixels wide are great for the forum to display properly - some folks post larger the they resize to fit the screen anyway.

Make sure that each image has its own unique file name - if you use the same name, the previous file will be over written.

Please post your coin up right (not sideways (us old folk here can get sore necks pretty quickly.

other than that, read the instructions found on the image up-load dialog box.

and one last thing - only one coin per topic, create as many topics as you need.

Here is a link on grading: https://www.pcgs.com/photograde/
Chances are your coins will not grade high enough to justify sending them in. Post up a couple good quality photos so we can help you out.
