Pakistan mint state, proof or specimen coins?

[srsnum]

The coin images below are submitted for comment. The coins were acquired more than 35 years ago. I am not sure if they are mint state, proof, specimen or ??  I have submitted the reverse only due to image number limitation of 8 per post.

The jury rigged setup I am able to afford does not allow for proper colors. Please make allowances for same.

Appear to be proof.

Thank you Pabitra for your response. Below, for the sake of completeness, find the obverse images, in same order, for the reverse images above.  Also find an image of the green, inside back cover of the holder in which they came (10.8x8.0 Cm). 

Although, I named the coin images as 'proof', it should be noted that the folder itself, though indicating that the coins were struck in West Pakistan at the Lahore mint, does not indicate explicitly that the coins are proof.  This has always been of concern to me.

Permit me to ask a last question.  Were the 'proofs' known to be issued in the simple green holder shown or were the 'proofs' issued in a different type of holder?

Looks like proof coins to me. The KM catalog lists a set of 7 proof coins, dated 1948, with 5000 sets minted. KM also lists a specimen set but I think these would not be issued in a box and would not have coins with such polished surfaces.

Proofs have a shiny field and matte raised elements. Mint state is a recent US invention. I am not sure whether it exists or is just a commercial gimmick. Prooflike coins are shiny all over and also have no bag marks. The difference is that prooflike coins are not struck with polished dies.

When I was just another innocent collector, specimen coins were marked with the word specimen or similar in another language. I would argue that piedforts (double or triple weight coins) are more or less in the same category as specimen, though.

Many thanks to Pabitra,Henk and Figleaf for their responses to my post.  Their clarifying posts have given me confidence in the proof attribution.  I feel safe in putting this mystery to bed.  Below, for completeness, find some improved images of the holder in which the coins are housed.
