Glasscoin Order #1/2 (mailed)

•November 24, 2008 • 19 Comments

These orders have been delivered and are now completed. Pre-orders continue on page #3.

Do not pre-order unless you are committed to purchasing at USD$15 per coin plus shipping and handling as your order will be used to calculate final sale price and limits. Orders from people who have previously defaulted will not be accepted.
Please place your caching name below and use a valid email address to be contacted. There is no payment required at this time unless you wish to order a track/untrackable set (made to order: immediate non refundable payment required.)


The coins pictured are for reference only: shown approximately life size, 1.2 inches square and 6mm thick; the glass is blue dichroic fully kiln annealed. It will have it’s own icon if all coins are sold otherwise be tracked on with the generic icon. PC prefix (not AU as shown).

Dichroic ie. two colour, glass has a special coating which ‘shifts light’ between two colours. The glass for the turtle used is pink/teal or magenta/blue; it’s not a misnomer but in the hand you do not see pink unless the glass is transparent – on black you see an irridescence from turquiose to peacock blue. The glass used for the tracking side will vary. At this time the lizard design is only available as an untrackable and cannot be ordered yet.

As they are handmade by various glass artists variations will occur in shape, size and colour. Air bubbles are an intrinsic part of the design but unpredictable.

How tough are they? Think of your playing marbles or a thick drinking glass. If you intend to release your purchase I would suggest also providing a plastic coin flip or upgrading the bag to a velvet pouch.

*USD$15 – these are handmade in the USA everything bar the bag but even that comes from a US supplier.
*If 100 coins sell we get an icon.
*LE Capping this design at 150 trackables on this blue dichroic glass and maximum of a 150 untrackables.
*If you would like to order a track/untrackable set the price is USD$25 +p/h fully prepaid and non refundable*. send money by paypal to:seachange_au@netspace.comThere will be an unspecified delay on mailing the set as the untrackables will be made up only to order.
*In the event of a mint no show on the untrackable, the trackable alone will be sent and the $10+ any postage difference refunded. Orders for sets will take priority over unpaid bookings.

There are 40 only for this pre-order currently in produuction; no guarantees of any future orders/designs. Successful bookings will receive a confirmation e-ticket. Purchasers of this turtle design will be notified in advance of any others and have pre-sale access.

You will not be invoiced until the coins are made. You will have 5 days to pay from invoicing after which a defaulters list will be posted to this thread. (I would like the option of decreasing the price and offering an untrackable so as the final pricing will be based on the number of actual orders so DO NOT preorder unless you are committed )

More Aussie Geocoins

A present from Cheesey pigs! awesome. Thank yousoooo much. I have looked a long time for this coin as it brings back happy memories of ‘personal best’ caching and thought it unlikely to ever add one to my collection. I moved one for Robtas in 2006 and it’s still stuck in the mr tack’s cache “my fair lady” if anyone wants to go see one in the wild that’s the place!

And from the world’s first choclate coin – untrackable great for events. The dark chocolate is quite hard as is the fondant layer – cold today perhaps! They are not belgian smooth melt in the mouth chocolate so it should travel well. Of course we inspected each coin thoroughly 12 yo prounced them really yummy!

Rainbow Glass Coin

•February 8, 2008 • 3 Comments

Walking into a glass shop is like walking around a rainbow made solid. Very hard things to photograph because of the translucency. The weight and smoothness is wonderful part of the experience too – we can throw the things across the room no trouble on carpet – I tried it!

There’s so many different ways to make a glass coin. I want to try them all! The hardest design element is actually the tracking and text. One option is to hand engrave the finished items but we’ll try it fired in place for starters. Here’s my design – black is etched into the coloured glass before being fired
