Question to the Q man:

1) To what extend does man made objects (glass, porcelain etc.) influence
the value of a carrier shell?
2) Should there be shells of value on the carrier, to what extend does it
affect the value of the carrier. For example, if there is a Lyria quekettii
on the shell should the value of the carrier be at least 25% or 35% or 50%
of that value?
