Please grade and value UK SILVER [επιλυμένο]

Please I need help to grade my  coin, I found long time ago but I have  not clue about grade and value  today. So any  help will be great.

1/2 Crown - George V km# 818  - 1918
And
1/2 Crown - Victoria (3rd portrait)  km# 782  -1900





Thank  you.

No guarantees for correctness but in my books they would be: Victoria VG and F for George if I would ignore what seems to be wirebrushing marks but I would not so VG too.
Personally I would not pay more than their metal value.

As Idolenz said, VG+ and VG, both are common, so scrap +10% max

Sorry  again,  I'm  little  confuse about  bullion so please correct me  if I'm wrong,  silver £450 kg? so
0.45 per gr,   so the George  will  be around £6,50  ?  okay?

many thank's

On their Numista site on the bottom of the page under the Numista rarity is the current bullion value probably in your respective currency pound euro or dollar.

Bullion value is weight of coin times purity times the current metal price per unit of mass that you are using so for your sterling half crowns  14.138g x 0.925 x 0.43€/g = 5,62€  (for 30.10.14  14:35 GMT+1)
