No idea really, I sold the 3 or 4 I had in the 90's at around 300 to 400 pounds a piece. But on the odd occasions the MB bowl/vase shows up on eBay they have not attracted much interest and gone for less than 100. I had one footed vase in blue/black/gold that I let go in the last couple of years.

http://www.ysartglass.com/Ysart/EbayYwatch2002.htmFollowing list updated as data comes in (23rd Sept 06)The
17 minature vases/bowls are potentially:
(Where a height is given it was measured from an example but is not listed in the original catalogues.)
A size X & XI
C size X & XI
D size XI
N size 95mm
O size XI
Y size XII & XIII
AA size 60mm probably XI
IA size XI
RA size XI
SA size X & XI
MB size XI (Halfway between a vase and a bowl)
TB size XI although nominally 4.5 inches as footed clearly miniature
GC size XI
XD size 90mm
GE size XII
HF size 90mm
RG sizes IX (104mm) & 95mm
JH IX
JJ 100mm
YK X+
The following are small items rather than miniatures, but look good in a collection of miniatures. All are more common than the above miniatures, particularly the drinking glasses which are still found in sets.
YB size XI borderline as it is a drinking glass
QC size X & XI borderline as it is a drinking glass in these sizes
EE size XII (depends on height as technically a bowl)
GG is a candle holder not a miniature
BJ is a spill/match holder, not a miniature
QJ is a candle holder not a miniature
PK is a candle holder not a miniature
Surface decorated miniatures are unheard of. I have a unique sugar bowl and jug set with cane decoration from the earliest Monart period, non-catalogue but not really qualifying as miniatures, they are just small pieces. But probably the smallest surface decorated pieces extant.
