each style and company has a top marble...rareity and eye appeal is the ticket...christensen....anything the make but cyclone and guniea is alweay worth several hundred.... peltier----golden rebel and blue galaxy....theres even a green galaxy in this group....vitro----parrot---eight fingers---confetti---marble king---watermelon--hercules [or bruiser]--green hornet---dragonfly---ruby bee----wv swirls---marbles with aventurine or oxblood---akro---ive seen several of their marbles bring good money but since the big backhoe dig their value seems to be waneing....popeyes hybrids always get big attention...jabo...some of the classic runs are doin well but the attention lately on the joker runs and madyia runs of recent vintage...some are bringin over $100 bucks on ebay...these contain oxblood and aventurine....some has gold lutz....vintage handmade...collect what you can afford these will always be bringin the bucks back...sulphides---the one with the german general in it[i cant remem,ber his name right now] is BIG money and i saw a hitler sulphide at a show once for 25.000 it obvious the vendor didnt want to sell...china...the old senic chinas can bring several thousand bucks....other styles and types can bring fun money and are easy to sell and trade...id rather sell 500 10$ marble than one thousand $ marble....
the most valuable thing in marble collecting...imho...is origional packing ive seen 100 count boxes of christensen sell for 25.000...an alley agate salesman sample box go for 20,000 and several more routinely sell for several grand....
