many thanks for the site,and yes someone put them in the ground and the funny thing is,it had to be many years ago,the family lived there for twenty years and have no kids.they said it must have been the family before them.first ill find out what there worth then ill try to find the family who lived there then.
The link TonyinCt gave is a good site for marble prices. I couldn't get any picts to download though, but they are a good reference site. I would look into them though ,because certain marbles like coins are valuable. One would never think so , but some certain types and colors are very hard to obtain and worth a fair chunk of change . smg
