Buying silver in Norway.

Inspired by @movingman 'expeditions' to Numisma Mynthandel shop i decided to take a visit myself yesterday. Numisma Mynthandel has been around since 1985 and is one of the largest coin traders in Norway. The store looks kind of old fashioned from the outside in a sweet way. As i was window shopping i saw the owner standing outside smoking his pipe. He was kind of the archetypal person you would hope to find running a store like this, in his sixties, big white beard smoking a pipe! He politely invited me to take a look inside which i did. What a cozy place it was! In the middle of the shop were showcases containing coins and medals of various eras. What i was looking after though was small silver bullions.
At the present moment they only had one type/size of bullion available. One ounce silver from 'Den Norske Myntverket' and that was what i bought. Here is what it looks like:

On the shiny front side is the logo of the producer along with a serial number. Curiously enough there is no weight indication engraved on the bullion! This mini piece is measuring 5x3x0.5 cm and is placed into a plastic case. It is tempting to take it out of the case but that change the grading from 'mint' to 'proof' (although i am not 100% percent sure about that). I'll probably try to find something that is sold without a casing to begin with.
The back side looks like this:

As you can see there is a matt finish on the back side with minimal info engraved. The letters Ag are the chemical symbol for silver and 999 denotes the purity of the silver (999/1000.)
I have no idea what the letter chi in a 'circle' mean. If anyone knows please comment.

How much did i pay? 200 NOK which is around 20 euro/22 usd. This is a higher price than expected due to the 25% added tax and a bit of seller profit. One ounce silver bars start from around 185 nok online (Edit:that is before tax and sending costs though!)
The shop owner mentioned that new stuff arrive constantly so i think i'll be checking in again soon!
