I have a question that long-time collectors might be able to answer readily.

The US Mint sold coins with a "satin" finish in its Uncirculated US Mint Sets from 2005 - 2010.

From 2011 and onward, the US Mint sold coins with a "brilliant" finish in its Uncirculated US Mint Sets.

Question: what type of finish were on the coins in Uncirculated US Mint Sets before 2005? Were the coins general circulation coins placed into mint sets? Were they hand-picked for quality?

Thank you in advance.

There were numerous, countless, different finishes between 1965 and 2005. Most would be termed "brilliant" but there were many textures and the brilliance varied from year to year and even from one mint set to the next. But there are also various types of PL's that appear in almost every date as well as variations in die preparation from year to year and set to set.

Mint set coins began being made differently than circulation issues in 1965 and in this year and 1966 many different techniques were employed that greatly affected the appearance of the coins. They vary from full (brilliant) Proofs to cameo highly PL to specimens that look like polished slugs. You name it and it appeared in a SMS. Production was "standardized" by 1968 but there are still variations in die preparation. Most of the oddballs are quite scarce. One of the more common ones is '81-P quarters that sometimes have nice smooth surfaces in about 5% of cases. Smooth surfaces can be tough on early '80's coins.

Thanks Cladking. Your answer provides an explanation of why some coins in US Mint cello's are not very eye-appealing. I guess if one is picky about quality coins, then coins outside of US Mint cellos should be purchased.

Me I like those coins which you HID: you say no eye appeal. I love to see because will pop me up any varieties better then PL or other mirror kind without take the any tools. The problem with those when you go to grade, will be lower then must be. The way TPG's work.

The most common reason coins in mint cello are unattractive is that for some dates almost all of the coins still in cello are tarnished. Most of the coins were attractive enough before they tarnished and the tarnish can usually be completely removed with acetone.

Of course there are other reasons like heavy marking or planchet marking that some are ugly.

For most moderns there just aren't any (or very few) BU rolls. This especially applies to dimes and quarters but now days even the coins that were saved the BU rolls have been split up.

BU roll coins are not immune from tarnish or spotting but it is far less prevalent.

To restore what was, a simply boiling bath in 40% boric acid for 2-3 min. will bring back the original and not more. This apply to Ni and AG. The Cu I will not go enter this door because is very touch.

Thank you. I'll try this.

Do you ever have an adverse reaction with the exposed copper on the edge of the clads?

No, just if I do not rinse with very hot water will become red-red brownish.

I will post in a few minutes a photo of a very yellow JFK before and now.
