When To Pay For Certification?

In my opinion, if they were my coins, I'd wiegh the cost of grading them, say at ANACS, which offers a $10.00 service per coin, plus shipping and insurance each way.
You can visit sites like NGCCOIN.COM or PCGS.COM and look up the value of the coins when they are certified. Some people will send coins in if the coin is valued at least 2x the grading cost or more.

For you, If its not so much the value, but you'd like to protect your coins, the holders can do that for you. It also gives you piece of mind, know that if something happend to them, they could potentially be replaced since there was documentation for insurance purposes.

I'm not going to take the time to look up the values of these, but in the end it boils down to what you want to do. In the future you can weigh in the cost and time alloted when searching for the coins, and the added expense of sending these in for grading, plus the time to do so. Then look at what one of these may cost already graded and slabbed by a major third party Grading service ( TPG) like ANACS, PCGS or NGC. Sometimes, the already slabbed coin may be an easier bet. It depends again on what you like to do...buy them or find them...

In most cases, if you're just seeking certified coins, you're better off buying them already slabbed. PCGS and NGC are expensive if you're going with their plans. PCGS seems to look good with "free" grades, but once you factor in all the costs the grades are far from free.

In general, the only time I send something off for grading is if it's really special and the slabbed value will be $150-200 or greater. Also, I have slabbed some lesser coins because they were important to me and I had no plans to ever sell them....stuff I want kept "in the family" for a long time.

The 1910 Lincolns are just not that valuable, I wouldn't send one in unless I think it had a shot at 65/66+.
