Those are really nice grade. More often than not, the 'silver' pieces are found with little to no coating/plating, and the iron beneath will occasionally have rust spots.
Most of these are relatively common Lauer made pieces. These will have come from different sets, as there is a mixture of young head, jubilee head and diamond jubilee pieces in here. While mostly common, these are still desirable due to the good condition.
The piece on the bottom right (brass model penny) is made by Joseph Moore of Birmingham. There are many different varieties/dies for this series, covered by a book by Tony Barter which is available online (I think the website was called blurb - printed to order).
The only piece which I don't immediately recognise is the top right (brass/gilded jubilee Victoria head/St George rev.).
Hope this is of interest.
