Howdy undrpar--
You definitely have a good hunting site. Congratulations on your excellent finds! You didn't post a picture of the reverse of your coins so in case you didn't know, I thought that I'd give you a heads-up that the mint mark (or lack of) is a significant factor in determining a coins value. Also, there are some Barbers that yield high $'s for specimens that are not harshly cleaned. For example your 1913 dime, if it's got an "S" mint mark in uncleaned Good to Fine condition can easily bring $25-90. Your 1893 Quarter in Fine to Extra Fine condition with an "O" mint mark could bring from $40- $130; with an "S" mint mark From $85- $185. Even the more common Barber's, especially half dollars, in Very Fine or better condition, in uncleaned state of preservation can be worth well over $100. Just thought that I'd mention that cleaning these beautiful old coins can reduce their value by 50% or more. Not that monetary gain is the sole reason why we metal detect but it sure is fun to find something of value and preserving that value. Here is a good source for determining an approximate value of U.S. coins:
