I have 2 George V gold sobereign coins of 1917 without ceca.

I think are fake.

Can Yoy help me?

Hi

I take it that by “ceca” you mean mint mark?

There are two listings for the one sovereign coin for that year one with and one without mint marks.

This is the one without the mint mark 1 Sovereign - George V - United Kingdom – Numista which could be yours.

I would check the weight and dimensions of the items make sure they match up with the link above if they do not then there could be issues with the authenticity.

Hope that helps a little until a more knowledgeable person pops on to forum to reply.

These are the most detailed photos I've taken, using different lighting conditions to capture as much detail as possible. Do you think it's fake?

So did you check the dimensions to the link provided? What do you feel about the differences?

The coin should be 22mm across and 7.99g but I see your scales only go to one decimal place and the measurement device is not holding the rim edge of the coins so the reading isn't accurate - one edge should be on zero the other should hit the 22mm mark.

The only way to definitively know if they are real gold and its purity is to have them tested with an XRF machine which you should be able to access at a jewellers. Alternatively go to a coin dealer in your area and ask their opinion. 

If I had one with a difference in size and weight than is standard for these items I would be getting them checked out as I would be dubious about them.

Strange way to measure diameters but look like 21.5-21.7 mm.
