Hi, welcome to the Board.
The weight appears to be a regular Ysart Brothers period (Vasart) concentric with some mixed canes. The central cane is not seen as often as most of the others but I would not refer to it as "special". The other cross-type cane (yellow, blue, white) is also one that is not (so far) seen very often but is also not "special".
Some people might say that the weight was made by Salvador Ysart and that may be true. The canes in the outer rows are of a type that are also seen in weights with a "Y" cane, but are also known in lots of concentrics that do not have the "Y - so again, not really special.
An attractive gift weight that ten years ago would have cost about £10 to £20. But some collectors now seem to be happy to pay well into the £100s for a weight like this!
