That's what Aunts are for! I don't have any children of my own, so I spoil my nieces and nephews as much as I can afford to. After all, who else is going to take care of me in my old age!
You can also press quarters. If I remember correctly, this costs about $1
Just a heads up. If you are flying - do not put these in carry on luggage, Pack in suitcase. Got held up LONG time in airport security. Thought they were bombs. Had pennies and quarters. Had to use some kind of testers, pull them out, etc.etc. Took out 25 minutes. They told me to pack in luggage next time. Also got patted down, etc. etc. Daughter(24) was ready to kill me, even though she is the pressed penny Queen. Brought them for her!! I was the LAST person to board the plane. Later we laughed about it. Who would have thought her obsession with pressed pennies would have caused such a mess. Have fun!
