Not to split hairs... You can split hairs all you like, I actually appreciate it. I had though polyvinylcloride was an additive to plastics. Edited by NJ Bob

No problem. Yes, PVC is type of plastic (#3 recycling code).  http://en.wikipedia.org/wiki/PVCQuote:
Polyvinyl chloride, commonly abbreviated PVC, is the third-most widely produced plastic, after polyethylene and polypropylene. PVC is used in construction because it is more effective than traditional materials such as copper, iron or wood in pipe and profile applications. It can be made softer and more flexible by the addition of plasticizers, the most widely used being phthalates. In this form, it is also used in clothing and upholstery, electrical cable insulation, inflatable products and many applications in which it replaces rubber. |

What are satins? I never heard of this before Between 2005 and 2010 the US mint produced mint sets using a new process that was intended to enhance the look of the coins. They used a slightly higher coining force and special cleaning after stamping. The problem was the "satin" finish actually showed imperfections even more than the old brilliant finish. This resulted in a variation, like proofs but not as nice, for these coins. |

Very nice, Bob! I like how you can see the difference between the two. billymac and I created separate albums ( https://goccf.com/t/140999&whichpage=1 ), so you can't see the coins side-by-side like you can in yours. Interesting that we are all working on this at the same time! |

I've had a lot of trouble seeing any real difference between satin finish and business strike cents. For all the world they looked exactly the same to me. I agree, the satin doesn't really come through to well on the cents like it does the other coins. I did really like the satin quarters though |

Interesting and very nice presentation. Looks like something you would want to lay out at a coin show for presentation only. Really nice looking.

you should see a difference between 2009 satin finish and 2009 business strike cents.  only 2009 satin finish penny were made in 95% copper. These Cu cents will tone quicker too.  All other satin finish and business strike cents are Cu plated zinc. Edited by Penny4Me

Looks good! My only problem with those albums is after a while the coins kind of get stuck to the plastic. Removing them without scratching becomes problematic. Thats just my experience.

Thanks everybody.  I have to admit that I was so excited that I could finally see the difference between satins and business strike cents that I couldn't resist starting this thread. I'm not done yet, I still need to add a label at the top of the page. (I use a P-Touch printer.) My next project is to do something similar with Jeffersons but I don't have all of the coins yet. When it's ready I'll post pix. |

I haven't had any problems with the coins sticking to the Guardmaster pages and, although I understand your point, I don't think there is any greater risk of damage to coins in Guardmaster pages than there would be to coins in a flip. Also, putting coins into a Dansco type album has potential risks too. The clear slides can scratch the surface of coins. |
