Coding
 

As a dealer, I want to put stickers on my items that I bought. Can someone give examples of how to code an item so you know what you paid for it, so that you only know?

Never done this before, but 1=A, 2=B, 3=C, etc to 9, then just write out the price using the letters??

Pick a ten letter word or phrase with no repeating letters and assign a number to each letter. Voila, you have created a code.

Not sure if this is what you are looking for, but just replace numbers with the place in the alphabet. example $135 would be ACE, $225 would be BBE, $75 would be GE. To make it less obvious, just shift the alphabet, go in reverse, or have multiple letters that can represent more common numbers. Just keep it simple.

Thanks for the help. No more forgetting what I paid. :)

Dumbwaiter is a ten-letter word with no repeating letters that I once read antique dealers sometimes use for objects on display (so they, but not the customer, would know what they paid or wanted to charge based on the sticker). A quick search will find many such words.

Code
 

A coin collector friend of mine just reversed the numbers. If he paid 12.99, he wrote 9921 on the tag.

Pick denominations and use colored stickers. You don't need to know if you spent $113 or $125. Just mark it as being between $100 and $150. Or if you're working with larger cards than just use colored stickers for each $100 up to $1,000.

Keep it simple.

Add or subtract 5 to each digit of the amount you paid.

If you paid $180, that becomes 635, $27 becomes72, $39 becomes 84, etc.

Simple and easy to remember.

Mark everything up exactly 300% and you will know what you paid.

Also known as the Dean's Cards Code :D

There was a big antique store here in Louisville that used to charge $1 to enter the place. It was like a museum. They would hand you a little slip of paper when you entered that had the words "BRUSH CLEAN" on it with the numbers 1-9 and 0 under the letters. All their tags on everything would be something like BRH D-10. So that would be $125 minus $10 or $115. It was like doing algebra every time I went down there. Got a lot of old split finger baseball gloves and some other miscellaneous BB memorabilia there over the years. Like someone said above, pick a phrase that works with 10 letters and just memorize it.
