There are some awesome coins posted here. When i first started collecting as a kid, all of my coins were change finds or whatever I could get for face value at the local bank. While in highschool, I had a football coach who was a retired professional player and an avid coin collector. He had the most beautiful set of raw Morgans and Peace dollars that I had ever seen and have yet to see again all together. He quickly became a mentor. He gave me my first Peace Dollar, a '23, and since I have added more to my collection. These were the first coins that I had ever paid more than face value for. For 35 years I have been waiting and watching for a nice '28 to come along that I could get without breaking the bank and several months ago, it did. After lots of negotiating, which included some trading and cash, I made a deal. Sent the guy some coins that I otherwise would have never sold and a money order and he mailed the coin. In anticipation I kept a close watch on tracking the package. It hit the main P.O. close to where I live and showed it left there headed to my local P.O. 50 miles away. It never made it. Somewhere it its last 50 mile journey it was lost. After months of dealing with the P.O. and negotiating again with the seller over a price for my trades, some of which he had already sold, I did get a reasonable refund, but am still extremely disappointed. Everytime I see a picture of a '28 I have to look to see if it is that one. Kinda like a lost pet.
Obverse looks like a go, assuming the reverse has a similar pattern of wear, then yes, you have an AU coin.
Explain to the newbe here why it is so important to put the coins in airtites compared to the squares ? Is it so they wouldn't be damaged by being stacked on one another ?
The squares allow for coin damage and toning that you would NOT want. Staple damage is far from uncommon. Moreover, the cardboard in the squares can tone a coin, which is a concern if you don't want it toned. Residue transfer from the plastic can take place as well.
