How Do You Track Your Collection Progress

That seems efficient enough. I use excel spreadsheets which I store on Dropbox so I can access them at a LCS or show, if needed.

I just have a small pocket notebook with lists of dates and mints that I need by denomination and series. as I acquire the needed coins I simply cross them out. this works good for me when I go to coin shows, the less that I carry with me the better.

Step 1: make a new sheet in my workbook
2: type in all the dates and mintmarks
3: buy the Whitman folder they will go in.
4: separate the dates with a blank row based on what goes in the folder
5: sort coins when I get them and separate them when ready to put into folders with the aid of the wotkbook
6: put coins in folder and delete row containing that coin from its sheet in the workbook
7: repeat starting at step 2 for new coins or new folder
7a: buy things like flips for San Fransico NIFC halves, 1973 Ike, foreign coins (excluding Canadian cents which have a Wargams folder)

I don't really keep track of the loose things like those in jewelry bags other than in an HTML page that shows all the coins I have foreign and domestic so I can look at a glance. No telling really how many NIFC halves and San Fran mint mark coins I have that aren't in folders, cause they just happen to be acquisitions that I am lucky to have, nothing really to try to make a set of. When it becomes enough they end up in coin tubes in a tackle box or ammo box with a sticker on top of the tube saying what is in it.

Also I have a printout of all US coins from Littleton or somewhere that use to know what types of coins are out there should I want to try a new set or get enough of a type that it requires me getting a book for, but 3 morgans, 2 peace, 2 Franklins, 2 walkers, are nothing really to get a book for so they reside in a cash box with my bill collection of few silver certificates and 2 seal and old style $20 bill and such.

Mostly it is just upon visual inspection of the folders.

For what you have pictured I would say a simple mobile device app so when you are out could help make sure you don't get an extra of something you don't want, and a spreadsheet for when you might be ready to go out and just write down the things you might want out if you are buying over-face coins.

I love using Coin Elite from Trove Software. Simple to print out data on any series in your collection or even the entire thing.

I have fewer than 10 coins that I need to keep track of. The rest are fairly inconsequential. For those 10 I have complete info written up in word and saved to dropbox for easy reference.

Looks like everyone has their own special way of
keeping track.

Some good ideas.

If you have an iDevice, you can use an app called uscoin. It backs up to a Dropbox account. It takes a while to log in the coins but once you get caught up, you then just log coins in as you buy them. I don't log every coin I have. Just the more valuable coins and coins in sets so I don't by duplicates.

For me.
Each coin is photographed and place into my IPhoto folders in which I can edit and also add info to each photo.
I also have them on power point as slides.
I do have a small collection of specialised, only about 500 coins and I am glad I don't buy everything.
I can recall and look at any coins straight away.
PS
I do carry a piece of paper in my wallet just for the rare ones
