Here is a 101 from my specialty collection of CD 101. Aqua with a nice carbon area associated with an internal air bubble right at the wire groove and dome. Embossed Brookfield on a raised bar with a #8 below. Hairline crack (glass is solid) right at the mold line on the left side. Crack runs from base to the wire groove. It is a hairline. Two small chips on the underside of the dome rim. $30 shipped in Continental US...more to other locations. See my other listing and save money on shipping. Embossed NO 9 on the reverse side.
