I need some tech help with extracting images from a PDF [επιλυμένο]

Unfortunately, being the wrong side (or right side, depending on which way you look at it) of 50, I am not quite so tech savvy as I would like to be. We had a coin listing submitted recently for the only coin known to have been issued in the name of Hywel Dda, a tenth century king who briefly united all of Wales and had close connections with King Aethelstan of England. The listing has now been published here https://en.numista.com/catalogue/pieces102744.html but as you can imagine, images of this coin are pretty scarce. There are a couple of images of this penny on a publication of the British Numismatic Society and they have very kindly granted us permission to reproduce them but they are on a PDF here http://www.britnumsoc.org/publications/Digital%20BNJ/pdfs/1982_BNJ_52_11.pdf and I could do with a little help to see if there is a way that we can copy these and upload them to our coin page (although I fear that even if we can they will be very low res). Anyone out there that can help?

Here are the pictures. Yes they will be poor quality.

It was done using the "PrtSc" key.

Zoomed in pictures, if you prefer

Thanks guys, much appreciated. It was no.1 that I was interested in, is it possible to zoom and enhance at all? I'll be out on the road all day but will get the pics uploaded tonight.

Here is the 01

Many thanks all for your help with this. I'll repost the link once the pics are added

As was to be expected, the pics are a tad fuzzy but thanks again to those of you that spent time to extract and enhance the low res PDF images and at least the listing looks more compete than just having blanks in place. I will email back to the British Numismatic Society to see if they have any better library pictures that we could use.

To do it yourself later, you can just download the PDF, and then put it in THIS converter. Then crop to get what you need.

Thanks Nathan, much appreciated
