Advice For Selling A Coin Collection?

No where did I ever see what type of coins they are and how many there are... Talking hundreds or thousands? Silver, gold included? Everyone has offered good advice so far.

Thank you for all the great advice!

First, I rearranged the coins by country.
Second, I rearranged the US coins by denomination.
Third, I set aside all the proof and mint sets.

Now I will start my research.


Thank you again and I will be sure to post pictures.

Since you have arranged your US coins by denomination, group each denomination by decade. It will make your research go a little bit faster.

Here are a few snapshots I took. Doesn't show any detail. Just the general piles I've create thus far.

Mint Sets:



Penny:



Nickels:

Dollars:



Random:



Foreign:



Proofs:

Jings, crivens, and help ma' Boab!!

But seriously, I was in a similar position a few months back, although I had collected coins as a wee lad with my grandmother-My grandfather ran a bank (introduced 1st drive through bank to UK, never caught on though lol) and so I was helped into my interest.
After having them all (improperly) stashed away for some 25-30 years, I decided I should dig 'em out, catalogue them and store them properly in 2x2's
I was amazed at some of the rarities and values that these command. I am not wanting to sell any (just now anayway) so the value is interesting in the fact that there is a good reason a particular coin is valuable, and so that makes it fascinating in my opinion.
With a more adult head (although only 34!) than when I collected them as a lad, I realise that this is something of substance and with enough variety/conjecture around many coins to hold an interest for many years.
If I were you, and not knowing your financial position etc (from your photos I would gather your coins could raise a considerable sum) I would hold on to them long enough to come across a coin which is 100+ times more valuable than the next, and see what that does to your constitution! I would guess that it would then become hard to part with them.
It's a strange tussle of the soul, knowing the value, yet not cashing in on it, forcing yourself to appreciate the alternative 'value' that these little round metal discs hold.
I collect rare books and literally hundreds of other things, all with a view of enriching the soul rather than the pocket, and I might venture to suggest that this(your coin inheritance) is something which could provide such fodder!
