hey Goldie
do you find those coin tongs are good to use?

I have often thought to get myself a pair as I am 100% clumsy and so frequently drop even my best coins (one very good reason for me to have slabs!!)

ps - I guess that it doesn't show the Blakesley Effect with being such a large planchet?

just found this on the Oz 3p blog
The Blakesley effect is not apparent on clips of the Australian 50c coin because the rims are formed during the striking process and not in a separate operation.

Robbiegal:   The tweezers, (Tongs), do help to hold the coin.   At rest, the tweezers will hold the coin.   Pressure on the tweezers will release the coin.   BEWARNED:   After many hours use, the plastic covering on the ends will/do wear through and need to be replaced somehow.   Like an old straw, slipped over the end, and melted/sealed with heat would suffice till the next time.

Many thanks for your responses.   That makes a second clipped 50c for me.

Thanks for the compliment.   All done on my scanner.

Some heatshrink tubing, preferably before the original plastic self-destructs, will do the trick nicely.

Well done Goldseeker!
I think I have found 2 as well.
My noodling had pretty much stopped with a number of fairly big things going on in my life taking up lots of time.
Keep us posted on your finds.  It's nice to see what is out there to be found.

Thanks for that Fulvio but it is a wee bit too late for me to do that.   I use the tweezers on my circulated coins only.

No probs.

BTW, these things are actually made by dipping the tweezers into molten plastic. It IS possible to replicate the process, but the temperature control has to be pretty precise, and of course you need the right plastic. Not something you'd want to do for a one-off. :angel:

This will do the job. Liquid Electrical Tape (http://www.jaycar.com.au/productView.asp?ID=NM2834)
Also available in black.

But, probably cheaper just to buy new tongs.

Ewwwwww.... No way!

"Chemical nature: Polymer resin in a suitable solvent system."

Look at the Hazmat warnings. No way am I letting that anywhere near my coins.

I think for $8 or $10 is much easier to buy the manufactured ones which I will be doing
