Hello and welcome Gina!
I cringed to hear what you've got invested in these marbles. I see mostly common stuff and some newer marbles, i don't think I see one Christensen in the bunch. I felt the need to comment and suggest that you step back and learn before you put out any money. Ebay is full of misidentified marbles and vultures looking to take your money. Just as you wouldn't jump in and start buying all sorts of stocks without learning what you are doing first, you want to learn what you are investing in and what is a good deal and what isn't. If those marbles in the group shots are what you have in to show for $1000, someone has taken advantage. I don't want to sound negative or discourage you, so I won't say how bad, but definitely don't keep buying from them. My mother got too enthusiastic about marbles years ago and overpaid for lots of them too, spending thousands upon thousands. She got some good ones in the process but lost quite a sum of money and without my knowledge. She took it upon herself to amass quite a collection without running them by me first. I don't want to see that happen to anyone else.
