Marbles - (1) Translucent Striped Swirl (Oxblood Blue Green) - Good to Near Mint

Please understand that I am not a marble dealer or appraiser, and the following information is provided to assist the buyer, but is subject to the normal dilemma presented by all unmarked, antique objects.  In other words, I may be wrong. 
Provenance:  I purchased this and several other marbles many years ago in a small town a few miles from the former (blankety-blank blank) Company in Ohio.
Ebay has indicated I can no longer utilize the actual brand name of the company as the representative who contacted me was allergic to spelling and did not understand that I was selling my marble collection, and not promoting the religion with a similar-sounding name.] 
Anyway, back to the story:  They were in a (insert ethnic name here) - labeled container that was rusted shut.  Very few of the marbles are actually perfectly round and or look machine made.  Most are odd color combinations with large pontils.  The glass compositions generally resemble older bottle glass.  After conversing with buyers who are marble dealers and long-time collectors, it would appear this may have been a marble-maker's collection - and perhaps includes some of the daily cast-offs.
I have received emails from users claiming that the marbles are modern (begins with a 'J', ends in an 'o') marbles, however, I have owned the collection longer than most of the runs that are referenced.  I have also measured ones that appear to be similar in color composition, and found that they are not the same size nor perfectly round, which would not be typical of modern manufacturing.
Based upon my research, this marble appears to be a (blanket-y blank blank) Translucent Striped Swirl.
The marble has a transparent base with swirls of milky white glass, Oxblood, green and blue glass.
There are several small surface marks, from both marble-playing and due to the vintage manufacturing process, that are visible in the photos.   
Please note that the images you are viewing are in excess of 10x the actual size of the marble, and some blemishes may not be visible in hand or on display.
Monitor colors may vary.
Many of the highlights are from windows and reflections of objects in the room, and I encourage you to compare the section in question in multiple photos to determine if it is a mark, bubble, or highlight.  I have labeled a few of the photos in other listings as examples of highlights that can occur in the room where the photos are taken.
A large number of detailed photographs have been provided in order for you to feel confident about the condition of the item, which according to a reputable site, appears to be Good to Near Mint.
Shipping reflects regular First-class postage with insurance and tracking.  Priority Mail is available at checkout and Expedited service is available upon request.

Please feel free to contact me for a l ink if you have difficulty finding it online.
Let's be friends.  Please read the following prior to bidding:
I would be happy to answer any questions you may have and send additional photos upon request, prior to bidding. Bidding is a commitment to purchase the item.
Upon bidding, you may receive an email from me requesting that you take a moment to review the contents of the listing, including the condition, details, price and shipping cost.  I cannot alter these items once the listing has received a bid.
Sellers incur fees immediately after an item is won, therefore payment must be received within 48 hours of the auction end.  Unfortunately, failure to pay for the item will result in a case being opened.  This is the only means sellers have to recoup their fees for an unpaid item. 
I am not a volume seller and do not accept returns at this time for any reason.  I do ship items with tracking and insurance to ensure they arrive safely, unless specifically noted in the listing and when prohibited by international mail services.  To-date, I have never had a package lost in the mail, however, delivery can be delayed significantly when sent overseas.
All of the items in my store are from my home or personal use, and will arrive clean, carefully packaged and free from any unwelcome auction house surprises.  I did not purchase the item listed above for resale, nor do I bid against you during the auction.
Every once in awhile, I completely disagree with the shipping calculator.  Please contact me if you are discouraged from purchasing the item due to shipping costs.  I always take the time to try to minimize the cost, whether it is to use a one-rate box or extend the shipping time at your request.
It would also be wonderful if you purchased more than one item, hint-hint, which would allow me to combine and reduce the shipping (often by 50 - 70% for the additional items!)
Items cannot be shipped until payment is received via PayPal.  I generally have the item to the post office the next day, however, I state in the listings to allow up to three days to compensate for auctions that end on Friday and due to unforeseen weather conditions. Please note the shipping estimate when bidding
and contact me in advance of remitting payment if you wish to upgrade your shipping.
I truly appreciate your interest!
